-----------
Canvas with float16 should use an extended DestinationColorSpace
https://bugs.webkit.org/show_bug.cgi?id=321163
rdar://184199283
Reviewed by Mike Wyrzykowski.
When a canvas is using a ColorType like float16 that allows for extended
dynamic range, and the system supports the corresponding PixelFormat
natively, attempt to use an extended DestinationColorSpace if
available.
No new tests, as existing tests should fail if there is any visible
impact.
