Same old gem_create but with now with extensions support. This is needed
to support various upcoming usecases.

the existing gem_create ioctl, otherwise we run into the issue

Add new extension to support setting an immutable-priority-list of
potential placements, at creation time.
If we use the normal gem_create or gem_create_ext without the
extensions/placements then we still get the old behaviour with only
placing the object in system memory.
v2
From: Matthew Auld
All userspace objects must be cleared when allocating the backing store,
before they are potentially visible to userspace. For now use simple
CPU based clearing to do this for device local-memory objects, note that
in the near future this will instead use the blitter engine.
From: Matthew Auld
Treat it the same as the fake local-memory stuff, where it is disabled
for normal kernels, in case some random UMD is tempted to use this. Once
we have all the other bits and pieces in place, like the TTM conversion,
we can turn this on for real.
