[HAL Device Manager] Available for request API + STA/STA request bug

Updated available for request API:
- Simple register/unregister API
- Will be called immediately on registration (if valid)
- Will be registered until unregistered
- Only a single copy is kept (duplicates detected)

Fixed issue whereby the requested interface wasn't counted toward
the total of required interfaces. So with only one STA allowed, a
second STA would have been allowed.

Bug: 34474043
Test: unit tests pass (with new unit tests added)
