Fix wrongly applied material theme for StandardMenuPopup (2nd attempt)

The second attempt contains followings
- Add feature flag for fixing this issue.
- Tweak the layout for not to be misaligned in some case.

Original comment from the first attempt:

The candidate windows has updated for Material theme but
it was done only for CascadingMenuPopup. The same things
need to be done for StandardMenuPopup which is mainly
used for the phone devices.

This CL also fixes the icon position wrongly aligned
to the left of the context menu for some case.
