Reenable pre-N style hard keyboard layout settings
This CL logically reverts Settings app changes for Bug 25752812, which
aimed to improve UX by tightly integrating physical keyboard layout
with input method subtype.
What went wrong is that the concept of input method subtype is not
widely accepted by the ecosystem actually. Until we figoure out any
other better way here, let's revert back to the good old way that
enables users to specify multiple keyboard layouts per physical
keyboard device, not one layout per one input method subtype.
Note that we cannot simply revert the CL that originally introduced
the new flow [1] because it was indeed a huge CL that also touched IME
settings, which we want to continue using. In that sense, this CL is
a kind of re-implementation of the previous style on top of the recent
language settings flow.
Note also that a fix [2] fox Bug 25062009 was also ported from
previous InputMethodAndLanguageSetting to
KeyboardLayoutPickerFragment.
