Merge remote-tracking branch 'origin/ue-symbol-based-receiver' into integration_2025_w43 (!3603)

UE symbol based PDCCH receiver

This is a partial rebase/rewrite of !2895

The goal of this MR is to check how we can merge this.

The eventual result is stated in !2895. The way forward is to modify UE
RX procedures to work symbol by symbol by extracting the symbol loop out
of RX procedures. After all channels are modified this way, the main
thread can be modified to work symbol by symbol.

At this point only PDCCH was modified.
