Pull gpu service/client shared memory buffer code to GpuMemoryBufferSupport

GpuMemoryBufferFactory is a gpu service concept and should
not be accessed from the client.

Client code accessed GpuMemoryBufferFactory to get the
native GPU buffer type and to check whether a provided
buffer is supported. Depending on GpuMemoryBufferFactory
ends up pulling in other service-only bits.

This CL addresses this issue. The two static methods
accessed by clients are pulled into a new class:
GpuMemoryBufferSupport placed in gpu/ipc/common.
