Improve desktop and mobile layouts for new "CommitGridView"

Summary:
Ref T13552. The current layout doesn't work particularly well on desktops or devices.

We have some device/desktop table layout code, but it isn't generic. We also have property list layout code, but it isn't generic either.

Provide generic layout elements ("Fuel", from "Phabricator UI Layout" to "PHUIL"?) and narrowly specialize their display behavior. Then swap the ListItemView stuff to use it.

Test Plan:
Saw slightly better responsive behavior:
