Add option to specify hard-coded TS types to a particular instance of the Monaco editor created using the module from {T2991}.
This is to enable autocomplete when someone is for example editing a snippet that will be used in a known environment.
There should also be an option to not provide any types.
Some discussion is likely necessary to make this happen in an elegant manner, hence this is 2 points. 1 point from that is to compensate for the design part.
