Add TextMatchMarkerListImpl

This is the last of the MarkerType-specific marker list implementations for now.
I'm also removing GenericDocumentMarkerListImpl in this CL since it's no longer
needed.

Right now this is very similar to CompositionMarkerList, but eventually this
will be the only marker list impl that creates RenderedDocumentMarkers, and I
will move the implementations of the text match marker-specific methods in
DocumentMarkerController (e.g. everything that has anything to do with rendered
rects) here.
