Anders Hartvoll Ruud cddbe4ad04 Bug 1698740 [wpt PR 28052] - Make :host()/:host-context() accept a single <compound-selector>, a=testonly
Automatic update from web-platform-tests
Make :host()/:host-context() accept a single <compound-selector>

This aligns us with Firefox/spec, and makes it possible to remove
the awkward dynamic specificity calculation code from SelectorChecker.

Added some basic parsing WPTs since it appeared to be missing.
