Call out IllegalArgumentException in docs for ImsMmTelManager

There are situations where the ImsMmTelManager APIs will
throw an IllegalArgumentException that were not explicitly called
out. These situations are now documented correctly.

Also internally moved to a SystemSpecificException that is
rethrown as an IllegalArgumentException in case we need to
add other Exception cases to the API.

Will follow up with API changes that deprecate the current
APIs and throw a checked exception instead.
