drm/xe: Convert remaining instances of ttm_eu_reserve_buffers to drm_exec

Browse source

The VM_BIND functionality and vma destruction was locking
potentially multiple dma_resv objects using the
ttm_eu_reserve_buffers() function. Rework those to use the drm_exec
helper, taking care that any calls to xe_bo_validate() ends up
inside an unsealed locking transaction.

v4:
- Remove an unbalanced xe_bo_put() (igt and Matthew Brost)
v5:
- Rebase conflict
