HDR 2D Canvas: Support for Float16 backend with put/getImageData
https://bugs.webkit.org/show_bug.cgi?id=297212
rdar://158032286
Reviewed by Mike Wyrzykowski.
ImageBufferBackend's support for Float16 image data, including
conversions between uint8 and float16.
In this initial "testable" implementation, setting the canvas pixel
format to float16 is enough to engage the display of HDR pixels.
