More flexible memory manager (#307)

* Keep track mapped buffers with fixed offsets

* Started rewriting the memory manager

* Initial support for MapPhysicalMemory and UnmapPhysicalMemory, other tweaks

* MapPhysicalMemory/UnmapPhysicalMemory support, other tweaks

* Rebased

* Optimize the map/unmap physical memory svcs

* Integrate shared font support

* Fix address space reserve alignment

* Some fixes related to gpu memory mapping

* Some cleanup

* Only try uploading const buffers that are really used

* Check if memory region is contiguous

* Rebased

* Add missing count increment on IsRegionModified

* Check for reads/writes outside of the address space, optimize translation with a tail call
