qcacld-3.0: Feature flag for Wlan Latency Manager support

WLAN Latency Manager support is one of the capabilities that is sent
along with the service bits by firmware. Currently, driver is not
exposing this feature to the user space.

Create and add support for a feature flag to expose this feature to the
userspace.
