Register a provider that returns data for the debugger's 'inline value' feature.
Whenever the generic debugger has stopped in a source file, providers registered for the language of the file
are called to return textual data that will be shown in the editor at the end of lines.
Multiple providers can be registered for a language. In that case providers are asked in
parallel and the results are merged. A failing provider (rejected promise or exception) will
not cause a failure of the whole operation.
