Rename inset-area to position-area
Per the CSSWG, this property has been renamed:
w3c/csswg-drafts#10209 (comment)
This does a mechanical rename:
inset-areatoposition-areainsetAreatopositionAreaInsetAreatoPositionAreainset_areatoposition_Area
After the mechanical rename, there were a handful of hand-fixups,
e.g. in cases where the old property (inset-area) needs to stay,
or in setting up feature access to both.
This CL also adds a surrogate from inset-area to position-area,
so that both names keep working. Separate runtime flags are created
to enable either of these property names. As-is, inset-area is
enabled for "stable", and position-area is "experimental". And
finally, a virtual test suite is added that enables inset-area
and disables position-area and tests that the old WPTs still pass.
Note that the WPTs had to be slightly modified for their new copied
location within the VTS.
