Expose camera caps via QGeoMap, add isValid() method to camera caps

This is useful to the QML plugin, so that map objects can be aware
of what camera actions to expect from their parent map. The isValid()
method is necessary so that callers can tell the difference between
a default, empty QGeoCameraCapabilities, and one actually populated
by a backend plugin.
