drm/amdgpu: rework how PTE flags are generated v3
Previously we tried to keep the HW specific PTE flags in each mapping,
but for CRIU that isn't sufficient any more since the original value is
needed for the checkpoint procedure.
So rework the whole handling, nuke the early mapping function, keep the
UAPI flags in each mapping instead of the HW flags and translate them to
the HW flags while filling in the PTEs.
Only tested on Navi 23 for now, so probably needs quite a bit of more
work.
v2: fix KFD and SVN handling
v3: one more SVN fix pointed out by Felix
v4: squash in gfx12 fix from David
