Update Typeface.createFromFile/Asset

This CL updates Typeface.createFromFile and Typeface.createFromAsset so
that they would use the Typeface.Builder. To keep the behavior similar
to previous behavior, the existence of the given font file is checked,
and an exception is thrown if the file does not exist.
