7c6faa1efe intel/aux_map: introduce ref count of L1 entries 
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.

b1a14fe923 intel: Return a bool from intel_aux_map_add_mapping 
Make intel_aux_map_add_mapping return false if a mapping is attempted
that would conflict with an existing one. If this function doesn't
return false, it will either fail to return or return true.

The Vulkan driver will make use of this feature to opportunistically
enable CCS if a BO's VMA range has not been already mapped.

47792b3642 intel/aux_map: Rename some variables to improve readability 
No changes in behavior here, mostly doing this types of renames:
- address to main_address, to know that addresses refers to main
surface address or aux surface address
- gpu to addr
- main_map_addr to main_inc_addr
- aux_dest_addr to aux_inc_addr
