Add back popover=hint functionality, behind a HTMLPopoverHint flag

This CL brings back popover=hint functionality. This does not include
the hover-triggering capability, which will be added back in a separate
CL. All of the new behavior is tested, some in the existing non-
tentative WPTs, and some in a fresh one. In the non-tentative WPTs,
feature detection is used to make sure it's only tested on supported
systems.
