video: driver: modify max mapped output count

adjust MAX_MAP_OUTPUT_COUNT based on resolution
to enhance performance and reduce memory pressure.
- For 8K session: count = 20
- For 4K session: count = 32
- For 1080p session: count = 48
- For all remaining sessions: count = 64

reduce MAX_DPB_COUNT to 32.
reduce DEFAULT_MAX_HOST_BUF_COUNT to 64.
