Optimizations of PDSCH Resource Mapping in nr_dlsch.c/nr_modulation.c

These changes add SIMD optimizations for Neon/AVX2/AVX512 in the PDSCH
transmit path. The timing improvements are listed here based on the

    nr_dlsim -e25 -R273 -b273 -s30 -x "layers" -y 4 -z 4 -P

benchmark with "layers" 2,3,4 and comparing "PHY proc tx":

Robert Schmidt 590850b03d Merge remote-tracking branch 'origin/issue_904' into integration_2025_w07 (!3257) 
Bugfix in gNB modulated DCI buffer size

Closes #904
 2025-02-14 15:15:40 +01:00
Bartosz Podrygajlo 16f028dba5 Dynamic PDCCH aggregation level 
The aggregation level search order for PDCCH candidates is modified:
 - the search starts from desired_agg_level_index, which is a value from 0 to 4
   proportial to pdcch_cl_adjust.
 - pdcch_cl_adjust is a value between 0 and 1 that indicates PDCCH channel quality
   by averaging HARQ DTX rate. A value of 0 means perfect channel, a value o 1 means
   impaired channel.
