[][MAC80211][WiFi6/7][Misc][Change group mgmt cipher setting to align group cipher]

[Description]
Change group mgmt cipher setting to align group cipher. Group mgmt cipher
is independent from other cipher, here we set it more intuitively. And
remain a way to directly set group mgmt cipher.
Before align Logan:
group cipher      CMAC-128  CMAC-256  GMAC-128  GMAC-256
group mgmt cipher CMAC-128  CMAC-128  CMAC-128  GMAC-256

After this patch:
group cipher      CMAC-128  CMAC-256  GMAC-128  GMAC-256
group mgmt cipher CMAC-128 "CMAC-256  GMAC-128" GMAC-256
