core(windows): remove code that caused location to be always accessed

[MSOB7YY]

while a windows version of the app is running, windows will show that the app is always accessing location, even tho location was never accessed or requested from the app code

im not sure why this block was added in the first place even tho the callback doesn't call any other code, i haven't done much tests but await Permission.location.request() returns PermissionStatus.granted normally

PermissionHandlerWindowsPlugin::PermissionHandlerWindowsPlugin(){
--  m_positionChangedRevoker = geolocator.PositionChanged(winrt::auto_revoke,
--    [this](Geolocator const& geolocator, PositionChangedEventArgs e)
--    {
--    });
}

List at least one fixed issue.

• windows no longer shows that the app is using location
• closes #1394
