media: uapi: Add V4L2_CID_STATELESS_HEVC_ENTRY_POINT_OFFSETS control
The number of 'entry point offset' can be very variable. Instead of using a large static array define a v4l2 dynamic array of U32 (V4L2_CTRL_TYPE_U32). The number of entry point offsets is reported by the elems field and in struct v4l2_ctrl_hevc_slice_params.num_entry_point_offsets field.
