Check for PDSCH overlapping CORESET during RA

CORESET 0 is configured in the configuration file by 'initialDLBWPcontrolResourceSetZero' and PDSCH TDA list is configured based on the current BWP size.

It may happen that the user configures a 2 symbol CORESET 0 for a BWP >= 48 PRBs (which is a valid 3GPP configuration) but in function 'nr_rrc_config_dl_tda' this scenario is not taken in account causing an overlap between PDSCH and PDCCH symbols during RA.

This leads to very unreliable Msg2 and Msg4 decoding at the UE, but from time to time it succeeds, which becomes hard to identify this issue.
