Add gpu::BufferBacking::shared_memory_handle()

Add gpu::BufferBacking::shared_memory_handle()

This CL adds a base::SharedMemoryHandle getter to gpu::BufferBacking.
The getter will be used by gpu::BufferBacking users when OnMemoryDump is
called to create base::SharedMemory dumps.

This is part of work for exposing SharedMemory usages on tracing
memory-infra dumps.
