Reworks GrGLGpu to track GL buffer state based on the unique
GrGpuResource ID. This eliminates the need to notify the gpu object
whenever a buffer is deleted.

This change also allows us to remove the type specifier from GrBuffer.
At this point a buffer is just a chunk of memory, and the type
given at creation time is just a suggestion to the GL backend about
which target to bind to for updates.
