FEATURE STATEMENT: - Introduce linear phase error noise model in Uplink at UE - Perform common phase error (CPE) estimation and compensation at gNB SOLUTION: - A linear phase shift model is introduced in simulation. - PTRS symbols are used to perform estimation of CPE from DMRS compensated signal - The estimated values are interpolated in time domain and signal is compensated for the CPE. - PTRS processing is done in Frequency Domain for each symbol in a slot and LLR's are calculated for each symbol accordingly. IMPLEMENTATION: * sim.h/channle_sim.c - Linear Phase Noise Generation model definition. * nr_ul_channel_estimation.c/nr_ul_estimation.h - CPE estimation from PTRS and DMRS compensated signal. * nr_dmrs_rx.c/nr_refsig.h - Regenerate PTRS symbols at gNB. * nr_ulsch_demodulation.c - Removed old PTRS processing code and move to a common PTRS processing function * defs_gNB.h/init.c - New PTRS variables definition and initialization * nr_ulsch_ue.c - Corrected PTRS parameter to get new PTRS symbols for each OFDM symbol TESTING * ulsim.c - Added Phase noise, Enable PTRS signal and verified the output. VERIFICATION - The LLR are rotated back with estimated CPE and no error is observed in scrambling/decoding

- replaced nr_slot_t with int as it was barely used in the code (also is defined after an lte struct) - removed use of phy_frame_config_nr from the UE (another file was created in SCHED_NR_UE, still the gNB file is used in some tests file at UE side)
