GpuService: introduce GetGpuMemoryBufferAttribs as a mojo interface

GpuService: introduce GetGpuMemoryBufferAttribs as a mojo interface

allow clients to ask for the aggregate list of supported
GpuMemoryBufferAttribs for all usage flags by querying
GpuMemoryBufferFactory before creating/importing a GpuMemoryBuffer.
    
we cache a list of GpuMemoryBufferAttribs here since these don't change
during runtime, and would require a way to update this list to support
dynamic GpuMemoryBufferAttribs.

Do we expect this list to change between requests? If not, can we cache it
during the first call, so that we don't have to do the work again for subsequent
calls?
