doc_nested_refdefs: new lint for suspicious list syntax (#13707)

https://github.com/rust-lang/rust/issues/133150

This is more likely to be intended as an intra-doc link than it is to be
intended as a refdef. If a refdef is intended, it does not need to be
nested within a list item.

```markdown
- [`LONG_INTRA_DOC_LINK`]: this
  looks like an intra-doc link,
  but is actually a refdef.
  The first line will seem to
  disappear when rendered as HTML.

changelog: [`doc_nested_refdefs`]: add suspicious lint for link def at
start of list items and block quotes
