This change removes
- GFX source files removed from the BUILD in #44401
- Extraneous unused Scenic includes in the same directory
(`//shell/platform/fuchsia/flutter/`)
- All remaining uses of the Scenic library from the Fuchsia SDK
- All remaining uses of fuchsia.ui.scenic.*
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
This change removes GFX and Scenic dependencies from Fuchsia integration
tests. Mainly, it:
- swaps out `fuchsia.ui.scenic.Scenic/GetDisplayInfo` for
`fuchsia.ui.display.singleton.Info/GetMetrics`
- removes the no longer necessary `fuchsia.ui.scenic.Scenic` connections
and component manifest declarations from tests
- removes any extraneous build deps tests have on `fuchsia.ui.gfx`,
`fuchsia.ui.policy`, and `scenic_cpp`

- [x] All existing and new tests are passing.
This change does the following:
- Refactors `engine.cc`/`.h` and `component_v2.cc`/`.h` to remove GFX ctors and callbacks.
- Removes `gfx_external_view_embedder`, `gfx_platform_view`, `gfx_session_connection`, their tests, and any supporting testing infrastructure (e.g. `fake_session`) from the build. This change does not delete the source files themselves in order to keep the change size smaller (as all these file deletions together are about another ~8K lines worth of deletions.) A separate follow up change will delete these files.

This change also:
- removes reliance from both tests on `fuchsia.ui.scenic.Scenic`
protocols
- migrates `touch-input-test` to get display info from
`fuchsia.ui.display.singleton.Info` instead of
`fuchsia.ui.gfx.DisplayInfo`
- adds support for `fuchsia.ui.display.singleton.Info` in
`portable_ui_test` to support the above
- migrates `flutter-embedder-test` to capture screenshots using
`fuchsia.ui.composition.Screenshot` instead of
`fuchsia.ui.scenic.Screenshot`
- updates screenshot tooling accordingly
- removes the embedding view hit test disabled case from `touch-input
test`, since disabling the hit region is not currently supported in
Flutter's integration with Flatland afaict ([this
logic](4f384979af/shell/platform/fuchsia/flutter/flatland_external_view_embedder.cc (L411-L434))
appears to set hit regions to the full view size by default, and
Flatland appears to drop the value
[here](4f384979af/shell/platform/fuchsia/flutter/flatland_external_view_embedder.cc (L578)))
- removes hit test configurability on `touch-input-test` and
`flutter-embedder-test` embedding views
Bug: fxbug.dev/125514
The change in [0] has propagated now everywhere, so we can use
`utf8.encode()` instead of the longer `const Utf8Encoder.convert()`.
Also it cleans up code like
```
Uint8List bytes;
bytes.buffer.asByteData();
```
as that is not guaranteed to be correct, the correct version would be
```
Uint8List bytes;
bytes.buffer.asByteData(bytes.offsetInBytes, bytes.length);
```
a shorter hand for that is:
```
Uint8List bytes;
ByteData.sublistView(bytes);
```

These sources have long been obsolete for most of the engine, except for the Fuchsia sources. They do not need to be built for any other platform so this PR moves them into a Fuchsia platform-specific build directory so that they are only present in the Fuchsia binaries.
Dart is being removed from the Fuchsia SDK, so remove references to it
here.
Also remove references to workstation_eng and replace with terminal.
workstation_eng is no longer a thing.
As we move the Dart FIDL bindings we need to stop calling FIDL methods
from Dart in the Flutter repo. This only affects some integration tests.
This moves the FIDL calls into C++ and uses platform messages to make
the functionality available to the Dart tests.
Remove reference to unused fuchsia.sys.Environment protocol in test
Realm setup. Besides being unused,
the reference was not correctly matched by an #include, nor a GN build
dependency.

Fixes https://github.com/flutter/flutter/issues/123307 - for Android, iOS, and Web, for the main display only (https://github.com/flutter/flutter/issues/125938 tracks supporting multiple displays, https://github.com/flutter/flutter/issues/125939 for desktop).
Desktop will need to be implemented for this, but given priority for a couple of our customers targetting foldable devices on Android I'm inclined to get this in before desktop can be finished.
The main concern for this right now is that on some Android foldable devices, setting a preferred orientation will cause letterboxing and the `MediaQuery` will _never_ get the full screen size when unfolded. This causes apps to think the screen is smaller than it is, as they've mainly been using `MediaQueryData.size` to figure this out. Android's recommendation is to not set a preferred orientation, and if you must to use the new method introduced in `ViewUtil.java` to calculate the maximal window size.
These keep turning up, so I did a little bash-fu to find them all.
```bash
grep -lL "#pragma once" $(grep -lL "#ifndef .*_H_" $(find . | grep "\.h$")) | cut -c 3-
```
This change migrates `touch-input` integration tests from the
`gfx-root-presenter-test-ui-stack` UI test realm variant to run
parameterized tests of two types: `gfx-scene-manager-test-ui-stack` and
`flatland-scene-manager-test-ui-stack`. Both are exercised for the
generic tap test, and only GFX is exercised for embedded view cases.
This will enable fuchsia.git to remove the
`gfx-root-presenter-test-ui-stack` variant, which will no longer be
supported.
This change also:
- removes or updates all remaining references of root presenter, which
manifested in the form of inline code comments
- adds a TODO to update the child view app for the embedded touch input
test cases
Note that this change does _not_ modify the `embedder` integration
tests, which use a generic `test-ui-stack` variant as defined by the
fuchsia pkg url:
`fuchsia-pkg://fuchsia.com/test-ui-stack#meta/test-ui-stack.cm`. Since
the contents of this package is defined in fuchsia.git, the realm under
test can adapt to changes in fuchsia.git so long as they update the
test-ui-stack build target (which they do in https://fxrev.dev/831359,
the change that relies on the touch changes in this repo described
above.)

Prepare Flutter's Fuchsia port for removal of the
fuchsia.ui.app.ViewProvider.CreateView() API.
The Flutter engine's implementation of the API, which has long been
deprecated, is removed.
Calls to the deprecated CreateView() in tests are replaced with
CreateViewWithViewRef().

This CL changes ERROR to WARNING for the logs when a child disconnects
and ChildViewWatcher is closed. This may happen due to other apps and
doesn't necessarily indicate a flutter error.
