Previously, the code only stored the MIP mode and transpose flag in the
relevant tables at the top-left corner of the CU. This information ends
up being retrieved in ff_vvc_intra_pred_* not based on the CU position
but instead the transform unit position (specifically, using the x0 and
y0 from get_luma_predict_unit). There might be multiple transform units
in a CU, hence the top-left corner of the transform unit might not
coincide with the top-left corner of the CU. Consequently, we need to
store the MIP information at all positions in the CU, not only its
top-left corner, as we already do for the MIP flag.
