drm/i915: Show pin mapped counts and sizes in debugfs

Browse Source 
Show a total and purgeable number of pin mapped objects
and their total and purgeable size.

Example output (new stat prefixed with a star):

  # cat i915_gem_objects
  19920 objects, 289243136 bytes
  19920 [18466] objects, 288714752 [267911168] bytes in gtt
    0 [0] active objects, 0 [0] bytes
    19917 [18466] inactive objects, 288714752 [267911168] bytes
  0 unbound objects, 0 bytes
  0 purgeable objects, 0 bytes
  1 pinned mappable objects, 3145728 bytes
  0 fault mappable objects, 0 bytes
* 19914 [0] pin mapped objects, 285560832 [0] bytes [purgeable]
  4294967296 [268435456] gtt total
