Merge remote-tracking branch 'origin/ldpc-aal' into integration_2025_w32 (!3344)

LDPC BBDEV/AAL rework

This branch aims to generalize the existing LDPC T2 implementation to support
other DPDK BBDEV accelerators, e.g., Intel ACC100/200.

Differences from the current T2 implementation include:
  1. relax CMakeLists.txt checking for custom dpdk-t2 implementation,
     technically, any DPDK BBDEV should work
  2. BBDEV capability checks during init
  3. llr_scaling to scale the input llr accordingly for better decoding
     performance on the Intel ACC100/200
  4. self-managed harq buffers for the ACC200, as internal harq memory is not
     available

Tested BBDEV devices:
  1. Intel ACC100
  2. Intel ACC200/VRB1
