Jan-Niklas Jaeschke fa75d3a60f Bug 1803355: Basic implementation of Custom Highlight API. r=edgar,emilio
Added WebIDL interfaces as per spec, added some necessary changes to support maplike and setlike structures to be accessed from C++.

Added `::highlight(foo)` pseudo element to CSS engine.

Implemented Highlight as new kind of `Selection` using `HighlightType::eHighlight`. This implies Selections being added/removed during runtime (one `Selection` object per highlight identifier), therefore a dynamic container for highlight `Selection` objects was added to `nsFrameSelection`. Also, the painting code queries the highlight style for highlight Selections.

Implementation is currently hidden behind a pref `dom.customHighlightAPI.enabled`.
