To implement this feature, we need to do CPU side tracking of all
L3/L2/L1 entries. This does add a little bit of CPU allocations, but
the advantage is that the traversal of the page table tree is faster.
No more need for the linear seach of find_buffer().
With this feature, we can have multiple VkImage bind to the same main
memory address, as long as they share exact same mapping parameters.
The AUX mapping will be removed when the last VkImage is destroyed.
As previously, if the L1 mapping entry parameters don't match, the
mapping fails. Anv handles this nicely by just disabling AUX on the
image.
