Enable dynamic label completions (#154)

* Support dynamic block label and dependent block completion

This adds support for completing the label for a given dynamic block and for completing the content for dependent blocks.

* Add test cases for dynamic blocks

* Enable nesting of dynamic blocks

* Enable hover for dynamic (and nested)

* Refactor semantic tokens for dynamic blocks

* Cleanup unused dynamic context

* Move dynamic-related logic under mergeBlockBodySchemas

Arguably the function now does more than merging, so it should probably be called something like "resolveBlockBodySchema", but I'm leaving that for another PR/iteration.
