video: driver: add check_session_supported for session admission

- check total mbps is within range(including current session)
- check total mbpf is within range(including current session)
- image session:
    - decode: Only non-secure allowed
    - encode: check basic image_encode requirements
        - wxh should be within allowed cap range
        - only linear fmt
        - input & output is 512 aligned
        - only CQ bitrate mode
        - GOP size should be zero
        - b-frame count is zero
        - timedelta based RC disabled
        - still-pic profile for 8bit and main10 for 10bit
- interlace resolution should be less than (1920*1088)/256.
- reject odd input or output resolution
- output resolution is with in inst->cap [min, max] range.
- current session mbpf is less than inst->cap[MBPF].max
