qcacmn: Add domain checks for precac and rcac

Write two new functions to check if preCAC and RCAC are supported in the
current DFS domain.

Currently, the preCAC is supported in the following DFS domains:
1. ETSI Domain

Currently, the RCAC is supported in the following DFS domains:
1. FCC Domain
2. MKK Domain
3. MKKN Domain
