[A11y] Fix regression and update support for aria-[row|col]indextext

The original property was called aria-rowtext and aria-coltext and
these were only supported because of an important use case in Sheets.
This was non-standards and was implemented anyway (shame shame). This
legacy support was broken via the HTML mode removal project, which
broke announcements for cell names in Google Sheets by having HTML
mode turned off by default on Windows. The reland of CL:5773586 to
completely remove HTML mode would have likely fixed the Sheets issue
but that stalled. A new reland is being worked on in CL:5827020 but
it doesn't address the new HTML attribute or platform API object
attribute names, and is too big/risky to merge into release branches.
It's also notable that the Sheets regression should have caught by a
test, but that test had been disabled due to flakes. This CL
reenables it.

As far as the new, longer HTML attribute names of aria-rowindextext
and aria-colindextext, in CL:5577953 enough support was added to satisfy
WPT tests but no platform mappings.

This CL updates the support so that both old and new HTML attribute
names are mapped to both the old and new object attribute names
(per CORE-AAM). Eventually, once Sheets updates to use the new
attribute names, the old HTML attribute names can be removed.
The old object attribute names need to stay to keep JAWS/NVDA
support.
