drm/amdgpu: Convert context manager to xarray

Browse source

IDR is deprecated so let's convert the context manager to xarray.

In doing so we remove the context manager mutex and switch call sites
which required the guarantee context cannot go away while they walk the
list of context, or otherwise operate on them, to use reference counting.

This allows us to use the built in xarray spinlock for all operations and
just temporarily drop it when we need to call sleeping functions.
