Support nav button color transitions
With this CL, the back and IME switcher buttons on the navigation bar
have the same color transition even when they are rendered by the IME.
Note that the behavior is still behind a flag
persist.sys.ime.can_render_gestural_nav_buttons,
which is still off by default. There should be no observable changes
no matter whether the flag is enabled or disabled though.
