Check status for every ISurfaceComposer Parcel

Add macro to check for the status when parceling and return the error if
failed. Also log the error when it occurs. Updated all callers in
ISurfaceComposer for transactions and screen capture to use the
SAFE_PARCEL call. Also updated all parceling in LayerState.

Test: Boots
