Use marquee for action items with super-long strings.

Where possible, try to fit strings onto two lines, then fall back to marquee if text is truncated.

Bug: 152624388
Test: Visual -- full strings are readable (if not pretty) across languages (ex. Greek, Georgian, Latvian, etc.)
Test: Visual -- When marquee is needed, all item messages are set to single-line marquee instead of two-line.
