WifiNative: Fixing some nits

Remove unnecesary static types defined in SupplicantStaIfaceHal and be
consistent with all the other API's in WifiNative. The layer below (i.e
WifiVendorHal, SupplicantStaIfaceHal, etc) should convert from
WifiNative type to the corrsponding HIDL type.

Also, WifiVendorHal can direcly accept a looper in it's constructor
instead of passing it a Handler Thread.

Bug: 36524196
Test: Manual test & unit tests
