wifi: iwlwifi: Add a new version for sta config command

Browse Source 
Add a new version of sta configuration command
which includes these wifi8 features:

1. LDPC X2 CW size support indication
2. Indication if ICF frame is needed instead of RTS
3. support for MIC padding delays for protected control frames
