Remove RemapAriaRolesDueToParent:
- It's harmless to have cells, rows etc. exist without a parent table.
  Having code in Blink to remap these roles causes complexity and
  issues with aria-owns. Adding any complexity to do this is more
  trouble than it's worth
- Remapping kListBoxOption to a kMenuItem when it's in a kMenu is
  related to old code inherited from WebKit. WebKit made efforts
  to try to change role=option or <option> elements inside a
  role=menu to menuitems, but this is just not worth it.

Also, 2 old tests that failed now pass, so the -expected.txt files
are removed -- the expectations were only there to allow the failures.
