imagebitmap: Use snapshot::Snapshot as bitmap data (#37131)

Browse source 
Replace the holder of actual pixel data of the ImageBitmap interface
([[BitmapData]] slot) from Vec<u8> to snapshot::Snapshot (image bitmap
with metadata).
https://html.spec.whatwg.org/multipage/#the-imagebitmap-interface

It will allow to have all required information (e.g. size, pixel format,
alpha mode)
for further drawing processing to/from canvas2D output bitmap.

Testing: No required tests
Fixes: https://github.com/servo/servo/issues/34112
