Use no-op-AltGr US-Qwerty XKB layout for certain CrOS 1P input methods.

These CrOS 1P rule-based (aka. "m17n") input methods remap characters
for layouts targeting ISO hardware with AltGr layers. However, they
currently use ANSI US-Qwerty XKB layout (without AltGr) as the base.

Without true AltGr at XKB level (albeit no-op i.e. no char assignments,
just XKB fallback to non-AltGr chars), attempts to implement AltGr at
higher m17n layer (atop Alt key events, as currently done) are futile.
Such key events can get captured by shortcuts and never reach m17n.

This CL must NOT be submitted until https://crrev.com/c/6301430
(landed @ R136-16213.0.0) has been included in CrOS LKGM version [1].
