We really want to remove font-kit from dep tree, so this is the first
step into removing raqote from servo. While vello_cpu is not perfect
replacement, I am confident that we will resolve all issues eventually:
https://github.com/servo/servo/issues/38345 (most important ones already
have PRs).
Reviewable per commit.
Testing: Existing WPT tests.

Follow to the HTML specification and support of Blob as
ImageBitmapSource
to able use it as intermediate instance in "fetch() -> Blob ->
ImageBitmap" execution sequence.
https://html.spec.whatwg.org/multipage/#imagebitmapsource
The specification says what these steps must run in parallel
(outside the createImageBitmap task), but currently loading bytes from
Blob
and later image decoding happen in synchronous order while
promise is fullfilled or rejected on bitmap task source.

Testing: Improvements in the following WPT tests
