driver: Add RRM-related definitions to driver interface

Add definitions for RRM (Radio Resource Measurement) support:
1. Flags that specify the RRM capabilities of the underlying driver
2. Flag for RRM in Capability Info field in Management frames
3. Indication in association parameters regarding an RRM connection
