Camera: Fix focal length/aperture tests for foldables

For foldable devices, depending on fold/unfold position,
the focal length of the camera may not be the same as
the supported focal lengths in the camera characteristics.

Adjust the test such that if the camera is a logical multi-camera,
the focal length/aperture is allowed to a value supported by
the active physical camera.

This adjustment is necessary for foldables because the "default"
focal length or aperture of a logical camera may be different
depending on the fold/unfold state.

Test: Run Camera CTS on foldable device
