intel/debug: Control start/stop frame of batch debug

Browse source 
When using INTEL_DEBUG=bat, INTEL_DEBUG_BATCH_FRAME_START and
INTEL_DEBUG_BATCH_FRAME_STOP can limit dumping of batches for
particular frame ranges. Batch dumps are huge. Smart filtering
allows debugging of single frames during game play. Initial
commit to debug infrastructure.
