Loïc Sharma 9792c4bd03 Reland "[Windows] Move to FlutterCompositor for rendering" (flutter/engine#49726) ...

## Original pull request description

This migrates the Windows embedder to `FlutterCompositor` so that the engine renders off-screen to a framebuffer instead of directly onto the window's surface. This will allow us to support platform views and multiple views on Windows.

Addresses https://github.com/flutter/flutter/issues/128904

## Reland (again)

https://github.com/flutter/engine/pull/49262 was reverted as it regressed [`package:material_floating_search_bar_2`](https://pub.dev/packages/material_floating_search_bar_2/versions/0.5.0). See: https://github.com/flutter/flutter/issues/140828

This pull request is split into the following commits:

1. d337378a74 is the previous reland pull request, unchanged
2. e866af0229 disables the scissor test before blitting the framebuffer, allowing us to "force" copy the framebuffer's contents by ignoring scissoring values
