The fuchsia code around metrics and sizing was just sending this
information through a side-channel, when the engine already had the
information available. So, delete all of it to make future CLs simpler.
Additionally, the SceneUpdateContext has many unneccesary dependencies
re: metrics and PaintTasks. Break those to make future CLs simpler.
Tested: Ran all unittests and ran workstation on Fuchsia

Refactors instantiateImageCodec and decodeImageFromPixels to provide intermediate data about the image width, height, and bytes per pixel. This allows for more fine grained control from Dart, particularly when trying to reason about how or whether to maintain aspect ratio in the targetWidth/targetHeight parameters.
This leaves the existing methods functional by re-implementing them to use the new ImmutableBuffer/ImageDescriptor class.
The ImmutableBuffer class is provided so that callers can avoid copying the image data multiple times if they wish to re-recreate the image descriptor.
Related Issues
Adds an `allowUpscale` parameter to the Dart interfaces for instantiateImageCodec and decodeImageFromPIxels. If set to false, the image bounds will be clamped at their intrinsic dimensions.
A later commit will change the default to true.
SkImage references get held by both our Image and Picture objects. The GC has no idea about this, and so sometimes pictures look very small when they're actually holding a reference to a large chunk of memory. This patch helps make sure that the GC can more adequately catch the real size impact of Picture objects, and combined with an upstream patch in Dart allows for much more aggressive collection of unused image related memory.

Constructing colors using `fromRGBO` should return the same values as the CSS
`rgba()` notation. rgba(0, 0, 255, 0.5) is the same as `#0000ff80`
However `fromRGBO` sometimes creates a color with an off-by-one alpha value:
expect(Color.fromRGBO(0, 0, 255, 0.5), Color(0x800000ff));
Expected: Color:<Color(0x800000ff)>
Actual: Color:<Color(0x7f0000ff)>
If we use `withOpacity` to create the same color, it returns the correct color:
expect(Color.fromRGBO(0, 0, 255, 1).withOpacity(0.5), Color(0x800000ff));
This should also be changed in lib/web_ui/lib/src/ui/painting.dart in a
followup change.
Make ImageFilter objects comparable and printable.
This will help in areas in the Widget and RenderObject trees which try to avoid marking objects for updates if a setter is called with the same value (previously all ImageFilter objects would compare as not equal and appear to be new values).
This removes TextRange from the framework and moves it to the engine, in preparation for using it to return text ranges from the text extent APIs, like Paragraph.getWordBoundary instead of a List<int>.
Also added new tests for TextRange.
Without this, developers have to override `onReportTimings` to listen for `FrameTiming`.
That can potentially break previous `onReportTimings` listeners if they forget to call
the old listener in their new callback.
This PR replaces the similar RP in the framework: https://github.com/flutter/flutter/pull/38574
Once this PR landed, we'll have to create another framework PR to use the stream to replace
`onReportTimings` usages.
Once that's done, we can then propose the breaking change of removing the deprecated
`onReportTimings`.
