Support willReadFrequently for CanvasRenderingContext2D
https://bugs.webkit.org/show_bug.cgi?id=244117
Reviewed by Darin Adler.
It's used to indicate there will be frequent get image data operations,
in which case an accelerated canvas can be slower than unaccelerated
one. This patch turns off hardware acceleration for the 2D canvas when
willReadFrequently is true in settings.
