Remove the ::media::gpu namespace which conflicted with ::gpu

We should not have sub namespace with the same name as top level
namespaces since that causes name lookup conflicts. ::media::gpu
in particular was only used by a single function, and I'm sure
it will be fine in ::media instead, saving us from having to
write ::gpu everywhere.

This broke the build in certain jumbo build configurations.
