anv/sparse: add the initial code for Sparse Resources

This giant patch implements a huge chunk of the Vulkan Sparse
Resources API. I previously had this as a nice series of many smaller
patches that evolved as the xe.ko added more features, but once I was
asked to squash some of the major reworks I realized I wouldn't be
able easily rewrite history, so I just squased basically the whole
series into a giant patch. I may end up splitting this again later if
I find a way to properly do it.

If we want to support the DX12 API through vkd3d we need to support
part of the the Sparse Resources API. If we don't, a bunch of Steam
games won't work.

For now we only support the xe.ko backend, but the vast majority of
the code is KMD-independent and so an i915.ko implementation would use
most of what's here, just extending the part that binds and unbinds
memory.

v2+: There's no way to sanely track the version history of this patch
in this commit message. Please refer to Gitlab.
