ts_31_10x: add a class for CardApplicationXSIM

In change Id410489841bb9020ddbf74de9114d808b1d5adb6, the RuntimeState
class automatically adds additional files to the CardApplications for
ISIM and USIM. This works only once. The second time an exception will
be thrown because the added files are already in the CardApplication.
Currently there is no way generate new card applications during
initialization because the card applications are just objects that are
created once in ts_31_10x.py. Lets turn them into classes and create the
objects during initialization. This way we get fresh objects when we
re-initialize.
