Add CHROMIUM_ycbcr_422_image extension.

Add an extension that provides a method for GL to process images that
are defined in '2vuy' video format.

GL_YCRCR_422_CHROMIUM <internalformat> as been added and it is an accepted
value when creating an image if the extension is supported.

This extension maps to GL_APPLE_ycbcr_422 and will allow us to determine if
we can use IOSurfaces with that format.
