This is part of an effort to separate generation of
host artifacts and target artifacts for fuchsia. The
`fuchsia_host_bundle` template aims to capture all the
artifacts that are specific to a given host.
The next step would be to bundle these are separate CIPD
packages for mac and linux (only x64 hosts)

Adds repeatCount field to KeyEventChannel.FlutterKeyEvent. We set it
to the value returned by KeyEvent.getRepeatCount() and add it to the
message passed through the channel with the intention of exposing it
in RawKeyEventDataAndroid on the framework side.
flutter/flutter#42855
This re-enables thread safety checks for WeakPtr. WeakPtrs can't be used on a thread other than the one the WeakPtrFactory was created on.
This fixes the unit tests and adds a getUnsafe() method to WeakPtr to work around the remaining unresolved locations where we are using WeakPtr unsafely.
The contents rendered into the backing stores are already correctly scaled.
The initial implementation assumed this also held true for the metrics obtained
via embedded view parameters.

Adds a task runner, and exposes API to allow application-level runloops to know when they need to next call the API to process engine events. Internally, sends null events to wake up the app runloop when new events are scheduled to ensure the wait time is updated accordingly.
Fixes#36420
Embedders may use this to specify a thread whose event loop is managed by them
instead of the engine. In addition, specifying the same task runner for both
the platform and render task runners allows embedders to effectively perform
GPU rendering operations on the platform thread.
To affect this change, the following non breaking changes to the API have been
made:
* The `FlutterCustomTaskRunners` struct now has a new field `render_task_runner`
for the specification of a custom render task runner.
* The `FlutterTaskRunnerDescription` has a new field `identifier`. Embedders
must supply a unique identifier for each task runner they specify. In
addition, when describing multiple task runners that run their tasks on the
same thread, their identifiers must match.
* The embedder may need to process tasks during `FlutterEngineRun` and
`FlutterEngineShutdown`. However, the embedder doesn't have the Flutter engine
handle before `FlutterEngineRun` and is supposed to relinquish handle right
before `FlutterEngineShutdown`. Since the embedder needs the Flutter engine
handle to service tasks on other threads while these calls are underway,
there exist opportunities for deadlock. To work around this scenario, three
new calls have been added that allow more deliberate management of the Flutter
engine instance.
* `FlutterEngineRun` can be replaced with `FlutterEngineInitialize` and
`FlutterEngineRunInitialized`. The embedder can obtain a handle to the
engine after the first call but the engine will not post any tasks to custom
task runners specified by the embedder till the
`FlutterEngineRunInitialized` call. Embedders can guard the Flutter engine
handle behind a mutex for safe task runner interop.
* `FlutterEngineShutdown` can be preceded by the `FlutterEngineDeinitialize`
call. After this call the Flutter engine will no longer post tasks onto
embedder managed task runners. It is still embedder responsibility to
collect the Flutter engine handle via `FlutterEngineShutdown`.
* To maintain backwards compatibility with the old APIs, `FlutterEngineRun` is
now just a convenience for `FlutterEngineInitialize` and
`FlutterEngineRunInitilaized`. `FlutterEngineShutdown` now implicitly calls
`FlutterEngineDeinitialize` as well. This allows existing users who don't care
are custom task runner interop to keep using the old APIs.
* Adds complete test coverage for both old and new paths.

Prerequisite for https://github.com/flutter/flutter/issues/17579
* Support empty strings and vectors in standard codec
Fixes#41993
Currently an empty string or vector will call through to WriteBytes
which asserts that the number of bytes it is being asked to write is
strictly positive. Instead we should not call WriteBytes if the length
is zero.
Similarly, when we read, we don't need to call out if the length is
zero.
* fix typo in test name
* remove unnecessary length check in ReadValue for List
* we also don't need this check before calling read as memcpy can handle size 0
This Pull Request simple adds the deviceId property to the encoding method, I am preparing a next PR on the flutter repository that reads this info and add a property to RawKeyEventDataAndroid on the Flutter side.
This is necessary so we can support multiple gamepads on Android, in order to be possible to make a local multiplayer game with Flutter.
So it's the same with the GPU thread.
Otherwise, some shaders may be cached in binary on the IO thread, and we will lose them when we do the SkSL precompile.

* [dart_aot_runner] Complete the port of dart_aot_runner
- also adds the previously missing profiler symbols for dart_jit_runner
- CIPD package will contain both the JIT and AOT dart runners
* specify the inputs
Since this is currently only meant to be used by the embedding internally, the setter in Objective-C is only exposed via the FlutterDartProject private class extension. Unit tests have been added to the shell_unittests harness.
