Merge remote-tracking branch 'origin/liteon_refactor' into integration_2026_w11 (!3864)

remove xran_fh_tx_send_slot_BySymbol() and xran_fh_rx_read_slot_BySymbol()

We have separate functions ran_fh_tx_send_slot_BySymbol() and
xran_fh_rx_read_slot_BySymbol() for liteon. This MR is to remove those separate
functions. 

Main author: Teodora Vladić
Co-author: Mario Joa-Ng

Changes:
xran_fh_tx_send_slot() is using if then else to handle per slot and per symbol
logic. xran_fh_rx_read_slot() is straightforward.

Testing:
- Liteon: Verified end-to-end.
- Benetel: (per slot without beam_id): Verified end-to-end.
- Microamp: (per slot with beam_id): Verified end-to-end. The branch
  microamp_F_harmonize is used instead as microamp could not be run with develop
  branch.
