Rollup merge of #142758 - jieyouxu:rustdoc-json-types, r=Kobzol 
Make sure to rebuild rustdoc if `src/rustdoc-json-types` is changed

I think `rustdoc-json-types` was more recently split out, so this download-rustc logic became outdated as it wasn't tracked. This PR adds `src/rustdoc-json-types` to be tracked for difference versus upstream, so that we properly rebuild rustdoc if it has changes versus upstream.

Fixes rust-lang/rust#142738.

### Local testing

This is not so easy to test locally because it requires download-rustc. To test this, you need to:

1. Disable `download-rustc` inhibition from bootstrap changes versus upstream, by including `:!src/bootstrap` in 255aa22082/src/bootstrap/src/core/config/config.rs (L67-L74).
2. Then, use a config like `profile = "tools"` which by default uses `download-rustc = "if-unchanged"`.
3. Run `./x test tests/rustdoc-json` one time, to "prime" initial build caches.
4. Change the `FORMAT_VERSION` in `src/rustdoc-json-types`, i.e.
	```diff
	diff --git a/src/rustdoc-json-types/lib.rs b/src/rustdoc-json-types/lib.rs
	index 1f93895ae07..72a3720c7b4 100644
	--- a/src/rustdoc-json-types/lib.rs
	+++ b/src/rustdoc-json-types/lib.rs
	``@@`` -38,7 +38,7 ``@@``
	 // are deliberately not in a doc comment, because they need not be in public docs.)
	 //
	 // Latest feature: Pretty printing of inline attributes changed
	-pub const FORMAT_VERSION: u32 = 48;
	+pub const FORMAT_VERSION: u32 = 666;
	```
5. Observe that without this patch, `rustdoc-json` tests fail because `FORMAT_VERSION` mismatch. Observe that with this patch, rustdoc gets properly rebuilt and `rustdoc-json` tests pass.
