Cleans up header order/grouping for consistency: associated header, C/C++ system/standard library headers, library headers, platform-specific #includes.
Adds <cstring> where strlen, memcpy are being used: there are a bunch of places we use them transitively.
Applies linter-required cleanups. Disables linter on one file due to included RapidJson header. See https://github.com/flutter/flutter/issues/65676
This patch does not cover flutter/shell/platform/darwin. There's a separate, slightly more intensive cleanup for those in progress.

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.

Relands #17489 with a fix for the unit test flake.
The previous unit test relied on the new instance not being created at the same memory address, which isn't guaranteed.
Seems to have triggered flaky failures on the Windows bot since landing.
Example failure:
[ RUN ] PluginRegistrarTest.ManagerRemovesOnDestruction
c:\b\s\w\ir\cache\builder\src\flutter\shell\platform\common\cpp\client_wrapper\plugin_registrar_unittests.cc(149): error: Expected: (manager->GetRegistrar<PluginRegistrar>(dummy_registrar_handle)) != (first_wrapper), actual: 000002400A90E3D0 vs 000002400A90E3D0
This reverts commit faf44fed5a5913dcbeebd7ead8e3933a5e72a6fc.
This makes two changes:
- Adds a way to register a callback for when a FlutterDesktopPluginRegistrarRef is destroyed, and implements the logic to call it in the Windows and Linux embeddings.
- Adds a class to the C++ wrapper that handles making a singleton owning PluginRegistrar wrappers, and destroying them when the underlying reference goes away, to avoid needing that boilerplate code in every plugin's source.

In generated text fixture location lookup code:
When the second argument to write_file() is a list, it is written one
item per line to the path specified by the first argument. This ensures
that we emit a trailing newline at EOF to comply with -Wnewline-eof.
Elsewhere:
Lack of a newline at EOF was undefined behaviour prior to C++11. The
Fuchsia tree sets -Wnewline-eof in its buildroot, so we plan to do the
same. This cleans up remaining first-party C++ sources that don't
include a trailing newline.
Changes include:
- File structure
- Header guards
- Include paths
- Namespaces
- Integration with the engine's GN build
- Conversion from jsoncpp to rapidjson
- Style and clang-format adjustment to match engine repository
