Sends the flutter/settings update message to the engine after starting
it. For now values other than 24-hour time preference are hard-coded,
but dark mode support can be added later.

Switches the Windows embedding from the standard C API to the new proctable version, to allow for unit testing of the embedding layer separately from the embedder APIs implementation. This includes moving some engine messaging that was still in flutter_windows to the C++ engine class to better encapsulate the proc table.
Replaces the (temporary) compile-time option to pass engine switches
with the ability to pass them temporarily at runtime via environment
variables.
This is enabled only for debug/profile to avoid potential issues with
tampering with released applicaitons, but if there is a need for that in
the future it could be added (potentially with a whitelist, as is
currently used for Dart VM flags).
Windows portion of:
https://github.com/flutter/flutter/issues/38569https://github.com/flutter/flutter/issues/60393
The Windows embedding was based on the GLFW embedding, which grew
organically from a singe-file implementation that used structs to manage
all of the important state. It is in the process of being converted to a
cleaner object-based architecture, but currently it is a hybrid of
objects and structs that have redundant data, making it very prone to
errors of forgetting to update pointers in multiple locations.
This reduces the remaining structs to only a single pointer to the
larger object that manages the responsibilities that handle is
associated with, so that there is no need to wire things together in
multiple places.
For now they continue to exist as projections of the larger objects, but
that will be eliminated over time by having an object structure that
better reflects the API structure.

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.

Refactors the Windows embedding internals to make an engine object that
owns things associated with the engine rather than the view, and updates
the API surface to allow using the engine directly.
This is an incremental step toward both a cleaner, non-struct-based
internal structure and a finalized API surface.
