Test that setPointerCapture in a different document fails.
Adds tests for the updated step 5 of setting pointer capture[1]
which expects that a pointer can only be captured to its
active document.
This relands https://crrev.com/c/5759832 selectively: includes the
same WPT change and omits the platform-specific expectation files
that have been removed.
