Nr ue fapi improvements

See merge request oai/openairinterface5g!618

however, I had to hardcode the parameters for the PUSCH in nr_ulsim as the fapi interface still has bugs.

This reverts commit 3574481b.

 - dci_request and dl_indication for PBCH now also on stack
 - fixed type of nrUE_config (was using structure for gNB before)
 - added configuration of PBCH to phy_config_request and using this config now in phy_procedures_nr_ue
 - we need to add configuration of PDCCH and PDSCH also to phy_config_request (there are still some hardcoded parameters)
 - removed UL scheduling for now

- This was due to alignment problem in rxdataF_ext when odd number of RBs were assigned

- Now it takes input and output pointers instead of gNB struct

- remove printf in nr_ulsch_coding.c
- renaming test_input to mac_pdu
- using memcpy for mac_pdu instead of pointing to data
- remove temp_nfapi struct from header file
