feature request: implement DocumentSymbolProvider to add marks to breadcrumb navigator

i just enabled the breadcrumbs view in VSCode. i'm looking for a way for marks to show up in the symbol navigator and breadcrumb navigator. i think they share the same data source, which are the registered DocumentSymbolProviders. it seems like the extension might need to call registerDocumentSymbolProvider() in order to do this.

i have no experience developing VSCode extensions, but if you're willing to help show me to ropes and give code review / feedback, i might be able to contribute this feature.

Interesting idea, thanks for the suggestion. Will keep this post dated on any progress.
