In order to show per client memory consumption, we
need tracking support APIs to add at every bo consumption
and removal. Adding APIs here to add tracking calls at
places wherever it is applicable.

V3:
  - update .h to return xe_drm_client_remove_bo void
  - protect xe_drm_client_remove_bo under CONFIG_PROC_FS check - Himal
  - Fixed Checkpatch error - CI
V2:
  - make xe_drm_client_remove_bo return void - Himal
