style: Un-prefix -moz-tab-size (keeping the prefixed version as an alias for now)

This results in lots of new WPT test passes.

There were also a couple of WPT tests that turned out to be broken;
tab-size-inline-001 and -002 had errors in their reference files such
that they'd never pass anywhere. So those are fixed here.

Depends on D117331
