Display: Refactor display property contexts

 - Delete redundant property contexts (sdm.idle_time, vendor.display.idle_time).
 - Rename gralloc debug property context to vendor_gralloc_prop.
 - Add ro.vendor.display and persist.vendor.display to vendor_gralloc_prop context.
 - Remove vendor property context for debug.sf.nobootanimation
   and qem.gles as these are system properties.
 - Remove ctl.ppd which is deprecated.
