sdm: Avoid fb_id creation and removal in each frame
- Cache the <handle_id, fb_id> map in SDM layer.
- Registry finds the handle_id in layer map. If it is found, then
mapped fb_id is programmed to DRM driver. Else fb_id is created
and it is added in map for the given handle_id key. This map is
cleared and fb_ids are removed, when the SDM layer gets deleted.
- "vendor.display.disable_fbid_cache" system prop needs to be set
to disable the fb_id caching in SDM. So, fb_id will be removed
and created for each SDM layer in every draw cycle.
