wifi: rtw89: debug: extend bb_info with TX status and PER

Browse source 
Enhance bb_info debugfs by adding TX status information to aid
debugging and performance analysis.

A snapshot of TX-related registers, including PPDU type and subtype,
bandwidth, TX power, STBC, etc. The information is collected per
PHY during track_work and displayed via bb_info debugfs.

TX status output:

  == TX General
  EHT_MU_SU DATA
  BW: 160, TX_SC: 0, TX_PATH_EN: 3, PATH_MAP: 0xe4
  TXPWR TMAC: 11, P0: 11, P1: 11 dBm
  MCS: 9, STBC: 0
  Info: [0x0000000b, 0xc1702c30, 0x0ff1e430, 0xc0000000, 0x99000009, 0x40000000]
  Common ctrl: [0x00000150, 0x40190140]

In addition, include the retry ratio from RA reports and display it
as PER (packet error rate) in station debug information.

PER output:

  TX rate [0, 0]: HE 2SS MCS-4 GI:0.8 BW:20 (hw_rate=0x324) PER:23
