Since you're in the process of making the top chrome and other system tooltips
conform to MD style, I'd vote for just landing this as being on by default. I
think it's the right thing to do (and would simplify this CL).

If this does land behind the flag, though, I'd suggest renaming this to
something like IsShelfTooltipMaterial() to clarify that they are for the shelf
app icons.

Done.
