In the change here b653a2823f, an intentional ABI breaking change was introduced to the clang runtime library for macOS and iOS. That change caused a symbol requiring dynamic linkage to be exposed that triggers iOS App Store checks for usage of private API.
This PR resolves that issue by rolling clang forward and introducing a definition of `_availability_version_check`. The declaration with weak linkage in the clang runtime library [here](b653a2823f/compiler-rt/lib/builtins/os_version_check.c (L89)) will then be resolved against the definition introduced in this PR. Since the declaration in the clang runtime library will now be resolved by static linking, the Flutter dylib will no longer require it to be dynamically linked, and will therefore not trigger the App Store check for using private API.
The definition of `_availability_version_check` is implemented using the `dlsym` strategy used by the old version of clang [here](f9ac557567/compiler-rt/lib/builtins/os_version_check.c (L97)).

Set gradle to treat warnings as errors and suppress or fix all warnings in engine android tests.

After doing this work I was disappointed to realized that the only lint turned on was deprecration but this is still a step in the right direction.
- Remove usages of deprecated junit.framework and replace with org.junit in KeyboardManagerTest, PlatformViewsControllerTest and SinglePresentationViewTest
- Annotate deprecated usages of Registrar
- Suppress warnings for getSystemWindowInsets and ensure roboletric config consistant with targetApi lint annotation, bump itDescribesTextFieldsWithTextAndHint to 28 because test actually fails on api 26
- Suppress warnings for DartExecutor.send
- Suppress warnings for ClipboardManager.set/hasText
- Suppress warnings for getWindowSystemUiVisibility, setMessageHandler, DartExecutor.send, InputMethodSubtype, and proof of concept migration from Roboletric.setupActivity
- Suppress deprecation warnings, set minsdk on tests that were checking for sdk version
- Suppress deprecation warnings in SpellCheckPluginTest
- Suppress deprecation warnings in MouseCursorPluginTest, set minsdk config to match target api
- Stop calling RuntimeEnvrionment.application and insted a call ApplicationProvider.getApplicationContext() in SingleViewPresentationTest
- Start calling FlutterView(Context, FlutterSurfaceView)
- Suppress deprecation warnings in PlatformPluginTest, getText, Robolectric.setup/buildActivity, system ui flags
- Suppress deprecation warnings in PlayStoreDeferredComponentManagerTest

- Suppress deprecation warnings in FlutterActivityAndFragmentDelegateTest
- Shadow.directlyOn is incompatible with java 17+, refactor to use reflectors and direct following https://github.com/robolectric/robolectric/pull/6598/files as an example Unsure if SplashShadowResources is used anywhere
- Enable warnings as errors
- Formatting
The simpler version I committed last week doesn't work correctly when
the texture has been transformed. This CL restores the old painting code
that properly handles this case.
Fixes internal b/296916021
Resolves https://github.com/flutter/flutter/issues/130947.
- Allow for setting the text renderer (`TextRenderContext`) when the
`AiksContext` is built. Previously, the text renderer was selected at
build time through linking a `TextRenderContext::Create` symbol.
- Support using Impeller without a text backend. Throw a clear error
when trying to render text if no text backend is present.
- Don't track the Impeller context in `TextRenderContext`. Just let the
renderer supply its context when generating atlases.
- Allow for overriding the `TextRenderContext` for individual Aiks
playground tests/goldens.
DisplayListBuilder grew over time from a class that implemented a developer-unfriendly stateful API into one that implemented both the developer-friendly DlCanvas API as well as its original stateful API. Over time, the stateful API was buried under a "testing only" facade.
In the meantime, the optimization features that it applies to the DlCanvas calls before it records the operations in a DlOp store are useful without the recording process and so I've been wanting to break those into 2 parts for a while with the goal of removing all stateful APIs from DisplayListBuilder (see https://github.com/flutter/flutter/issues/108303).
This PR takes a major step along that direction by splitting DisplayListBuilder into essentially a convenience class that marries 2 new classes together to achieve its old functionality:
- `DlCanvasToReceiver` - a class that implements DlCanvas, optimizes common situations, and then sends commands to any object that implements `DlOpReceiver`
- `DlOpRecorder` - an implementation of DlOpReceiver that records the operations in a buffer from which to create a `DisplayList` object
- `DisplayListBuilder` now inherits from DlCanvasToReceiver to get the optimizations and provides it with an instance of `DlOpRecorder` as the receiver that it will send its results to
- Similarly, a `DlCanvasToReceiver` instance could be directed to an `impeller:DlDispatcher` to achieve a more straight-through path from the DlCanvas interface to impeller Pictures.
## Description
This PR updates the Android engine in order to provide a more efficient implementation for `BasicMessageChannel.resizeChannelBuffer` (helper to call the `resize` control command).
It also adds a new helper called`BasicMessageChannel.allowChannelBufferOverflow` to call the `overflow` control command.

In the add-to-app scenario where multiple FlutterViews share the same FlutterEngine, the host application desires to determine the timing of attaching the FlutterView to the engine, for example, during the `onResume` instead of the `onCreateView`.
As an example, consider the following scenario: A native page contains multiple tabs, and each tab is a FlutterFragment. During initialization, FlutterFragments of different tabs are created almost simultaneously, but only the one that needs to be displayed currently requires attachment to the engine, while the others need to be attached only when they receive the |onResume| callback.

- Refactor AndroidExternalTextureGL into SurfaceTextureExternalTexture
base class with two specialized implementations:
- Add SurfaceTextureExternalTextureGL for legacy GL rendering.
- Add SurfaceTextureExternalTextureImpellerGL for Impeller GLES
rendering.
NOTE: There is still no support for SurfaceTextures under Vulkan
rendering.
For Google3, this makes it easier since we only need to make one source transform (from `#include "flutter` -> `#include "third_party` instead of requiring a source transform for every root directory in this repo.

Wires `application:openURLs:` into the exisiting delegation system, allowing plugins to handle URL callbacks (as on iOS).
Since there is no notification-based version of this delegate method, this adds it directly to the app delegate, restructring the helper class slightly to allow internal sharing of the delegate list.

The fuchsia.sys FIDL library, used to implement v1 components, is
deprecated in the Fuchsia platform and is being removed.
Flutter now implements Components v2 but still imports the old library.
Bug: https://fxbug.dev/109013
Adds `addApplicationDelegate:` to the macOS plugin registrar, following the corresponding iOS method, and wires it up to the existing app delegation forwarding that was recently added for use at the application level. (The actual delegate is non-trivially different between iOS and macOS, but that's not resolveable without a complex migration on the iOS side, so the APIs currently diverge after the level of the `addApplicationDelegate:` method itself.)
This doesn't add any new methods to the delegation; those will be added in a follow-up PR.
Also fixes a retain cycle in the termination handler that prevented the new test from working.
