Reduce number of times MD docs are re-tokenized (#152674)

Browse Source 
This change reduces the number of times we retokenize a markdown file by doing the following:

- Use `MdTableOfContentsProvider` in more places
- Introduce a `IMarkdownParser` interface that lets us drop in a caching version of the tokenizer
