Use memcpy in nr_prach.c to fill txdata buffer. Remove global tables related to PRACH generation. Add new function to compute modulo multiplicative inverse and use it directly to get inverse instead of LUT. Removed nr_ru table and compute the values in-place. In UE, added new flag root_seq_computed in nrUE_config to only compute the sequence once after new nrUE_config is received.
