media: cedrus: h264: Support multiple slices per frame
With recent changes, support for decoding multi-slice frames can be
easily added now.
Signal VPU if current slice is first in frame or not and add information
about first macroblock coordinates.
When frame contains multiple slices and driver works in slice mode, it's
more efficient to hold capture buffer in queue until all slices of a
same frame are decoded.
Add support for that to Cedrus driver by exposing and implementing
V4L2_BUF_CAP_SUPPORTS_M2M_HOLD_CAPTURE_BUF capability.

[[email protected]: removed unnecessary (u32) cast]
[[email protected]: use new_frame v4l2_m2m_ctx bool]
