qcacmn: Featurize WMI APIs and TLVs that are specific to WIN

In the existing converged component, WMI TLV APIs are implemented in
a generic manner without proper featurization. All the APIs exposed
outside of WMI are implemented in wmi_unified_api.c and all the APIs
forming the CMD or extracting the EVT is implemented in wmi_unified_tlv.c.

Since WIN and MCL have a unified WMI layer in the converged component and
there are features within WIN and MCL that are not common, there exists a
good number of WMI APIs which are specific to WIN but compiled by MCL and
vice-versa. Due to this inadvertent problem, there is a chunk of code and
memory used up by WIN and MCL for features that are not used in their
products.

Featurize WMI APIs and TLVs that are specific to WIN
- Air Time Fareness (ATF)
- Direct Buffer Rx (DBR)
- Smart Antenna (SMART_ANT)
- Generic WIN specific WMI (AP)
