Make it possible to distinguish xfail tests from regular skipped tests

### What feature do you want to see added?

Due to current limitation in junit format, xfail test may be reports as skipped with the extra information about xfail as `type="pytest.xfail"`.

Still, when these are rendered in the UI, there is no indication that these in fact did run and passed due to being marked as `xfail`.

While the `message` field is rendered, the `type` is not rendered at all. If the type will also be rendered this could be probably found as "good enough". Still, right now, is impossible to distinguish unless you dig into the XML file.
