Initial msm8x64 memory tracker HAL

Reads memory info from kgsl to track unaccounted for GL and ION
memory.  Right now it has to parse every allocation and then
cross-reference it against /proc/pid/smaps.  It would be faster
to modify the kgsl driver to keep counters that could just be
read directly.
