* [fuchsia] enable boot time shader warmup even when LEGACY_FUCHSIA_EMBEDDER is defined
* [fuchsia] decouple shader warmup from embedder api
* [fuchsia] change warmup context flush() to flushAndSubmit() to reduce memory footprint of warmup
* [fuchsia] Fix GPU resource lifecycle issue with shader warmup
This fixes an issue with the shader warmup where gpu resources could end
up deleted before the gpu work that needed them was complete, leading to
GPU page faults. This was because although the sk_sp<SkSurface> will normally
keep resources alive throughout its lifetime, the SurfaceProducerSurface will
call VkDestroyMemory on the memory backing the SkSurface when it is deleted,
even if the SkSurface wrapping that VkMemory is still alive.
This change also deletes some related but unused code from
CompositorContext that I noticed while refactoring.
This change contains a couple of changes that should have been in
github.com/flutter/engine/commit/3105db8ee856ffef281d018774d21a6164c81236
but fell through the cracks
First one lifts the initialization of the flutter::RunConfiguration so that
the asset manager gets set on the persistant cache before the shader
warmup happens. I'm not sure how this didnt end up in the first PR I
think it got mangled during merge conflict resolution. no test coverage
for that code because its in the middle of a 400 line constructor
Second one fixes a race condition that the tests dont catch because the
tests are single threaded. This change restructures the test that missed
this bug so that it would have caught that bug and will catch comparable
bugs.
* Revert "Remove GetExternalViewEmbedder from surface (#22272)"
This reverts commit 5419f70f173db1c9f2d5db4c289560e68ce9b77b.
* Revert "Rasterizer is initialized with an external view embedder (#22405)"
This reverts commit f95df42e6e3d80f17c2024e9956768be9416717f.
* Reland fuchsia external view embedder will be shared with platform view
This reverts commit 9b752790f4d25ab238576c719208d7a38c6293f3.
* wait for the external view embedder to be initialized before creating
shell
Snapshots compiled with sound null-safety enabled require changes to the way in
which isolates are launched. Specifically, the `Dart_IsolateFlags::null_safety`
field needs to be known upfront. The value of this field can only be determined
once the kernel snapshot is available. This poses a problem in the engine
because the engine used to launch the isolate at shell initialization and only
need the kernel mappings later at isolate launch (when transitioning the root
isolate to the `DartIsolate::Phase::Running` phase). This patch delays launch of
the isolate on the UI task runner till a kernel mapping is available. The side
effects of this delay (callers no longer having access to the non-running
isolate handle) have been addressed in this patch. The DartIsolate API has also
been amended to hide the method that could return a non-running isolate to the
caller. Instead, it has been replaced with a method that requires a valid
isolate configuration that returns a running root isolate. The isolate will be
launched by asking the isolate configuration for its null-safety
characteristics.
A side effect of enabling null-safety is that Dart APIs that work with legacy
types will now terminate the process if used with an isolate that has sound
null-safety enabled. These APIs may no longer be used in the engine. This
primarily affects the Dart Convertors in Tonic that convert certain C++ objects
into the Dart counterparts. All known Dart Converters have been updated to
convert C++ objects to non-nullable Dart types inferred using type traits of the
corresponding C++ object. The few spots in the engine that used the old Dart
APIs directly have been manually updated. To ensure that no usage of the legacy
APIs remain in the engine (as these would cause runtime process terminations),
the legacy APIs were prefixed with the `DART_LEGACY_API` macro and the macro
defined to `[[deprecated]]` in all engine translation units. While the engine
now primarily works with non-nullable Dart types, callers can still use
`Dart_TypeToNonNullableType` to acquire nullable types for use directly or with
Tonic. One use case that is not addressed with the Tonic Dart Convertors is the
creation of non-nullable lists of nullable types. This hasn’t come up so far in
the engine.
A minor related change is reworking tonic to define a single library target.
This allows the various tonic subsystems to depend on one another. Primarily,
this is used to make the Dart convertors use the logging utilities. This now
allows errors to be more descriptive as the presence of error handles is caught
(and logged) earlier.

Previously Skia did not require the clients to pass in the usage flags and Skia would just assumed they contained specific ones depending on how the client wrapped the VkImage. Now Skia allows the client to pass in the specific usage flags used so that Skia knows exactly what type of operations are legal without having to guess/assume what the client did.
Also update to set the sample count as well while I'm in here.
[fuchsia] add intercept_all_input flag support
This change also fixes an issue where FlutterRunnerProductConfiguration
crashes when a field is missing, when building with --unopt.
Test: Added unit tests
Bug: fxb/61466, fxb/61942
This change adds support for forwarding scenic's viewConnected,
viewDisconnected and viewStateChanged events to flutter. The
corrensponding change on fuchsia side is at:
https://fuchsia-review.googlesource.com/c/topaz/+/434356
Test: Includes unittest to verify the events are forwarded.

This change adds a response to the platform view message: requestFocus
This allows the caller to handle the case when the request fails with
an error value.

When Flutter engine connects to Scenic, Scenic has already
checked the display and graphics device availability before
Scenic starts; so it is guaranteed that display devices are
available and surface is valid when it is created.
Thus this change removes the device watching details from
flutter surface on Fuchsia so that it doesn't need to do
duplicated checks and hides the device-specific details.
Skia is removing the deprecated legacy display setting globals and
associated kLegacyFontHost_InitType. This change replaces all such uses
with default surface properties with no special flags and an unknown
pixel geometry. Flutter never set the associated globals, leaving them
with their initial default values, which were no special flags and
horizontal RGB pixel geometry. The values used here are different but
this change should make no difference as Flutter never mentions
SkFont::kSubpixelAntiAlias to take advantage of the pixel geometry.
