Subject: [PATCH] qcacmn: Add mcs, gI & sig info to cfr metadata

Add mcs rate, gI type and other SU sig info to cfr metadata.
For Tx based capture mcs rate & gI type is applicable

      1: 24 Mbps
      2: 12 Mbps
      3: 6 Mbps
      4: 54 Mbps
      5: 36 Mbps
      6: 18 Mbps
      7: 9 Mbps
      8: invalid entry
MCS for HT, 0-7: MCS0-MCS7,
MCS for VHT, 0-9: MCS0-MCS9,

ltf_size:
     0: he_ltf_1_x
     1: he_ltf_2_x
     2: he_ltf_4_x
dcm: Indicates if DCM set
     0: No DCM
     1: DCM
sgi: Indicates if short gI used
     0: No short gI
     1: short gI
beamformed: Is packet beamformed
     0: non-beamformed
     1: beamformed
stbc: Indicates if stbc applied
     0: No STBC
     1: STBC
Coding:
