Reason for revert:
Trying to unblock roll wedged on 64 bit intrinsic call on XP

> Use the GrCacheable ID to eliminate the need for notifications to GrGpuGL when textures and RTs are deleted.

> Also, rename GrCacheable::getGenerationID() to getInstanceID() since it doesn't behave like other "generation" IDs.

Remove use of SK_SUPPORT_LEGACY_LAYERRASTERIZER_API.

Mozilla have removed any uses of the legacy API from their Moz2D code.
Since they were the last users we know of, we can remove the legacy API.
