[WPT] Add Chromium blockquote style as a test expectations variant
The external indent.html WPT editing test has failures for two reasons:
implementation bugs and Chromium's blockquote style, which is applied
in IndentOutdentCommand::ApplyBlockElementCommand(). Failures caused by
the latter make it harder to identify those caused by the former. Since
the test harness supports multiple valid results, add a variant to the
current expectations that accounts for Chromium's blockquote style.
This change reduces the number of failures by 55 and makes it easier
to identify the remaining issues.
