Bug 1929347 [wpt PR 48976] - Implement basic structure for dialog light dismiss [1/N], a=testonly

Automatic update from web-platform-tests Implement basic structure for dialog light dismiss [1/N] This CL puts the feature flag in place, adds (flag guarded) closedBy and requestClose() methods to <dialog>, connects the pointer events handling to a new dialog light dismiss method, and adds a basic set of tests. None of the actual functionality is here yet, this is just a shell. Subsequent CLs will flesh out the behavior.
