This PR will fix the blank FlutterView issue by handling the repaint message in FlutterView window.
Currently, WM_PAINT msg is not handled in flutter window and the default WindowProc will do nothing but paint the background. In some user cases, e.g., hide/show/min/max the app window, this can result in blank FlutterView if the content is static and there are no running animation.

Updates scrolling in Windows to respect the 'lines to scroll per scroll wheel tick' setting at app startup.
The scrolling amount per tick is also increased to match Chrome (at 100px with default windows settings). This is also similar to what UWP does natively (approximately 96px based on observation).

This PR moves the pointer injector library from fuchsia views library
present in fuchsia.git to the flutter embedder.
Test: ffx test run "fuchsia-pkg://fuchsia.com/flutter_runner_tests#meta/flutter_runner_tests.cm"
`gdk_keymap_get_for_display()` does not transfer ownership to the
caller. Destroying the keymap object would cause problems further down
the road when `GtkWindow` gets to clean up and tries to destroy the
same keymap.
The runner is supposed to either serve the runtime_dir, or close the
channel immediately. Otherwise consumers will get blocked indefinitely.
BUG: fxbug.dev/103480
If the following is added to Info.plist of the application,
it will disable partial repaint:
```
<key>FLTDisablePartialRepaint</key>
<true/>
```
The primary intended usecase for this is to enable applications to see if disabling partial repaint resolves:

* Make FlAccessibleNode derivable
This allows introducing specialized subclasses that implement such a11y
interfaces as AtkEditableText that should not be implemented for the
generic node.
* FlAccessibleNode: add set value, text selection & perform action
Prepare API required for the upcoming AtkEditableText implementation.
* FlViewAccessible: postpone child node creation
This changes the a11y node creation flow so that (unknown) child nodes
are not pre-created when their parent is updated but "pending" child
node IDs are collected for later. Parent-child relationships are
established at the end of update batches when all nodes have been
created.
* Add FlAccessibleTextField that implements AtkEditableText
Solves: flutter/flutter#103191
* FlEngine: add fl_engine_update_accessibility_features()
* FlSettings: add API for high-contrast & animations
* FlEngine: allow passing mock messenger at construction time
* FlSettingsPlugin: report accessibility features
* Implement toGpuImage, a synchronous, GPU-resident version of
Picture.toImage.
This method kicks off asynchronous work on the raster task runner.
If it fails to rasterize, it will synchronously throw later when
the user attempts to draw to a canvas.
This supports several use cases:
- Quickly snapping off an expensive-to-rasterize image for reuse
across multiple frames.
- Applying multi-pass filters to a render target.
This patch amends flutter_tester so that it can produce an image
object, but that image will always be a grey and white four square checkerboard.
Adds support for CanvasKit on Web, which basically already used
this method for its Picture.toImage implementation.
Throws an UnsupportedError for HTML on Web, since any implementation
there would almost certainly be slower than drawPicture.
