qcacld-3.0: Refactor FINE_TIME_MEASUREMENT configuration

One of the HDD functions with the highest cyclomatic complexity is
__wlan_hdd_cfg80211_wifi_configuration_set(). In order to reduce the
complexity there is a plan to replace the inline attribute handling
with a vtable-based approach.

As part of that goal refactor the following independent attribute
handling into a separate function and add that function to the vtable:
- QCA_WLAN_VENDOR_ATTR_CONFIG_FINE_TIME_MEASUREMENT
