Accelerated convertImagePixels for PixelFormat::RGBA16F
https://bugs.webkit.org/show_bug.cgi?id=321147
rdar://158267620
Reviewed by Mike Wyrzykowski.
Remove the long-winded and unaccelerated float16 conversion functions.
Instead, add float16 support through the accelerated path.
Note: There is no need for unaccelerated float16 functions at this time,
since PixelFormat::RGBA16F is only available on platforms where
accelerated CG functions exist and should be used.
