tools/aubdump: Add bitmap to track gtt pages that have been mapped
This will allow us to map ranges as they are used, but prevents
remapping already mapped regions.
By mapping ranges as they are used, we can support pinned pages
without having to map all pages of the first 32-bits.
v2:
* Make bitmap manipulation functions independent from 4k page size.
Maybe will be usable also for 1GB pages with PPGTT.
