Develop nr fixes

See merge request oai/openairinterface5g!505

reverting some changes in the UE that were introduced by nr_polar_encoder_optimizations to make UE work again on real-time testbench. Now at least the PDCCH can be detected and used for time tracking. However, the DCI is not yet decoded (this will be fixed on branch nr_pdcch_fixes). The reverted changes are most notably passing the correct slot number to slot_fep in phy_procedures_nrUE. This will have to be changed as well in the future when we pass to slot-based processing at the UE.

Resolve "NR PDSCH: Deinterleaving and rate-matching are in wrong order"

See merge request oai/openairinterface5g!502

On the gNB side tha data are first rate-matched and then interleaved.
So on the UE side, the received LLRs have to be deinterleaved first before rate-matching.

This significantly improved the performance, especially for MCS values > 3.

Nr polar encoder optimizations

See merge request oai/openairinterface5g!463

temporarily disabling PDSCH decoding while finding the problem that makes nr-ue crash when used in real-time

adding nr_ue_scheduled_response to UE and fixed paramters in nr_ue_dcireq. Now DCI decoded again by UE.

adding function dci_req for UE
disabling handle_dci for now

adding Nid_cell to nr_pbchsim
