[uber page] Migrate the virtual keyboard sub-page to a dialog

[uber page] Migrate the virtual keyboard sub-page to a dialog

This also fixes a bug in OptionPage.getVisibleOverlay_ that assumes the first
overlay we find that's visible is the showing overlay (but doesn't account for
the nesting level of that overlay) as well as a language overlay confirm bug.

BUG=111685
TEST=./build/gyp_chromium -Duse_virtual_keyboard=1 -Dchromeos=1 -Duse_ibus=0 -Duse_aura=1
and open Advanced > Language settings > Keyboard and then actually close
language settings.

chrome/browser/resources/options2/chromeos/virtual_keyboard.html:1: <div
id="virtual-keyboard-manager" class="page" hidden>
should the file be called virtual_keyboard_overlay.html?

Yes, but I think this needs to be done on a bigger scale as there are tons of
_page instead of _overlay before I started converting. /cc jhawkins, csilv
