lib/ioctl_wrappers: Add gem_gtt_type exposing raw HAS_ALIASING_PPGTT param

Browse Source 
No functional changes.
While I'm here, let's also rename gem_uses_aliasing_ppgtt (since it's
being used to indicate if we are using ANY kind of ppgtt) and introduce
gem_uses_full_ppgtt to drop some unnecessary code from tests that were
previously calling getparam directly instead of using ioctl wrapper.

v2: drop gem_uses_full_48b_ppgtt since it's no longer used anywhere,
    s/48b/64b (Chris)
v3: rebase
