Adds APIs for runners to delegate WindowProc handlers into the Flutter
engine, and for plugins to register as possible delegates.
This allows for plugins to alter top-level window behavior in ways that
can only be done from the WindowProc, such as resize control. This
functionality remains entirely on the native side, so is synchronous.

Makes BinaryMessenger available from FlutterEngine, rather than just the plugin registrar. This allows for method channels directly in applications without building them as plugins, and matches the other platforms.
Requires some restructuring of code and GN targets in the client wrappers to make the internals in the shared section usable by the implementations of platform-specific parts of the wrappers. Also fixes a latent issue with EnableInputBlocking symbols being declared but not defined for Windows that came up during testing of the restructing.

Reland #19396 with a fix for improper scale that was affecting internal tests
Tested: Ran all unittests, ran internal tests, and ran workstation on Fuchsia
BUG: 53062, 53063
* Handle glfwGetPrimaryMonitor returning nullptr
[glfwGetPrimaryMonitor](https://www.glfw.org/docs/3.3/group__monitor.html#ga721867d84c6d18d6790d64d2847ca0b1) may return NULL in non-error cases when no monitor is found. This started to happen recently with an update to the linux distribution, see internal b/162545223.
Handling this case avoids a crash and instead assumes a pixel density.
A recent refactoring broke the USE_LEGACY_ENCODABLE_VALUE codepath in
standard_codec.cc, which went unnoticed since it wasn't being compiled.
This fixes the breakage, and also adds a temporary minimal unit test
target that ensures that all the USE_LEGACY_ENCODABLE_VALUE paths are
being compiled.
Queries the system list of user-preferred languages, and sends it to the
engine just after starting it up, as well as after any OS locale change.

__has_feature(cxx_rtti) is a clang extension, but clients of this code
are mostly using the VS toolchain. This makes the RTTI check work with
more compilers.
This improves raster cache control from apps and enables
GPU acceleration for some offscreen workloads that would
fallback to software.

This change creates the scenic session with request to Focuser. The
focuser is used to request focus to a view, given it's ViewRef. The call to
requestFocus is made from PlatformView messages channel, which will
be used from Flutter side by ChildView.
Adds a PlatformView unittest for the requestFocus method.

Standard*Codec allows for extensions to support arbitrary types; this
had not previously been implemented for the C++ version.
Overview of changes:
- EncodableValue's std::variant type now allows for a new CustomEncodableValue, which is a thin wrapper around std::any, to store arbitrary extension types.
- ByteBufferStream* has been split into an interface class and the buffer-based implementation, with the former now part of the public API surface to be used in standard codec extensions.
- They also gained utility methods for some common data types to simplify writing extensions.
- StandardCodecSerializer is now part of the public API surface, and is subclassable.
- StandardCodecSerializer's ReadValue has been split into ReadValue and ReadValueOfType to match the structure used when subclassing on the Dart side, for easier porting of custom extensions across languages.
- Standard*Codec now optionally accepts a non-default serializer in GetInstance, providing a shared instance using that serializer.

Changes the interaction between the view controller and engine in both the C API and
the engine API, so that there's always an engine (as on other platforms) rather than
the engine APIs being specific to headless mode.
While adjusting the C API, this does a large cleanup:
- Renames all methods to follow a `FlutterDesktop` (prefix) + "class" name + method-style name.
E.g., `FlutterDestkopViewControllerCreate` rather than `FlutterDesktopCreateViewController`.
This makes it easier to see what functions operate on which conceptual "object" in the API.
- Reorders and groups them by the object they operate on.
