Small refactor before actually dumping GLImageIOSurface.
Adds an additional helper template to GenericSharedMemoryId to allow
it to be used as a hash key as the first element of a pair. This is
very common throughout the GpuMemoryBuffer / GLImage system, where
objects are frequently keyed off of <GenericSharedMemoryId, ClientId>.
