A new source code/header structure was introduced when the DlColorSource and DlImageFilter objects were migrated to Impeller geometry classes. Even though the DlColorFilter objects did not depend on Skia geometry objects, they need to be updated to the new source layout for consistency.

Every text frame must inform the glyph atlas about the glyphs + scale it contains. When this happens, the glyph atlas will populate the glyph and then tell teh text frame about the location in the atlas, so that the text contents shader can sample it correctly.

Once this has been done once for a given text frame + scale + offset, we can actually just keep reusing the same data provided 1) the atlas itself hasn't changed and 2) the scale/offset/properties are the same.

This constitutes a nice CPU usage reduction in places where there is a lot of text that isn't being invalidated, like scrolling on the flutter gallery.

Changes the following shell callbacks to flush the dart event loop:

* OnPlatformViewSetViewportMetrics
* OnPlatformViewDispatchPointerDataPacket
* OnPlatformViewDispatchPlatformMessage
* OnPlatformViewSetSemanticsEnabled
* OnPlatformViewSetAccessibilityFeatures
Using a new TaskRunner API RunNowAndFlushMessages. If the task runner can run tasks on the current thread, this will immediately invoke a callback and then post an empty task to the event loop to ensure dart listeners fire.

Unlike #56738, does not touch the vsync API - which looks like it depends on scheduling behavior today, at least for iOS.

While recently updating the DlColorSource sources I noticed some questionably implementation choices in the Color variant of the color sources.

I then realized that there was no public use of these classes (other than mostly their own unit tests) and so they should be deleted to focus on implementing the variants that are actually used by Flutter.

…... (#56823)
