1. Set document selectors for capabilities, such that capabilities can only be triggered on documents that support them. Especially useful when registering multiple languages. 2. Dynamically register semantic highlighting capability (to test the former change, and make a start with registering all capabilities dynamically). 3. Instead of toggling the language for open editors, request a refresh of the open editors via LSP. This prevents races where requests can come in while the file is 'closed'. This PR is a preparation to easily enable #1117.

Looks nice! Just some small points.

while this is nice, it has no exec bound to it? isn't that a problem?

can we explain why we lock? who else might be doing this registration?
and why we lock for so long?
My concern is that the exceptionally handler that manipulates c is executed outside the lock (and not relocking).

| logger.error("Exception while unregistering {} ({})", u.getMethod(), u, t); | ||
| c.addAll(cs); |

same here, no lock here, is that fine? and if so, let's explain why.
