feat(health): show available queries for `treesitter` (#37005)

Problem: Outdated query files in `runtimepath` can trigger errors
which are hard to diagnose.

Solution: Add section to `:check treesitter` that lists all query 
files in `runtimepath`, sorted by language and query type. Files
are listed in `runtimepath` order so that the first of multiple entry
is typically the one that is used.

Note: Unlike the `nvim-treesitter` health check, this does not try
to parse the queries so will not flag incompatible ones (which would
be much more expensive).
