Camera: Use VNDK version to set feature combination query version

Between V and 25Q2, the ICameraDevice version doesn't change. So it's
not possible to set feature combination query version based on
ICameraDevice version.

Use VNDK version instead. Refactor isVNDKVersion so that it can be
called multiple times without incurring any performance hit.
