To me, this function doesn't seem like it belongs on the ActionHandler but
should just live within this class.

If we want the embedder to have the ability to toggle support for this, I think
we should have supportsTextProcessIntents as a function to keep it consistent
with the isSelectionEditable as below.  But for now, I would just include it all
in this file.

Okay. I just moved the related logic from contentviewcore to this class.
I don't add supportsTextProcessIntents() yet. I haven't seen any use case that
yet. People can add it easily when it is necessary.
