intel: tools: aub_mem: reuse already mapped ppgtt buffers
When we map a PPGTT buffer into a continous address space of aubinator to be able to inspect it, we currently add it to the list of BOs to unmap once we're finished. An optimization we can apply it to look up that list before trying to remap PPGTT buffers again (we already do this for GGTT buffers). We need to take some care before doing this because the list also contains GGTT BOs. As GGTT & PPGTT are 2 different address spaces, we can have matching addresses in both that point to different physical locations. This changes adds a flag on the elements of the list of mapped BOs to differenciate between GGTT & PPGTT, which allows use to reuse that list when looking up both address spaces.
