Check rustdoc-json-types FORMAT_VERSION is correctly updated
Follow-up of https://github.com/rust-lang/rust/pull/142677.
``@nnethercote`` suggested that we should also ensure that the `FORMAT_VERSION` was only increased by 1 and we should check for it, this PR does it.

centralize `-Zmin-function-alignment` logic
tracking issue: https://github.com/rust-lang/rust/issues/82232
discussed in: https://github.com/rust-lang/rust/pull/142824#discussion_r2160056244
Apply the `-Zmin-function-alignment` value to the alignment field of the function attributes when those are created, so that individual backends don't need to consider it.
The one exception right now is cranelift, because it can't yet set the alignment for individual functions, but it can (and does) set the global minimum function alignment.
cc ``@RalfJung`` I think this is an improvement regardless, is there anything else that should be done for miri?
Document subdirectories of UI tests with README files
Part of rust-lang/rust#133895 and the [2025 Google Summer of Code](https://blog.rust-lang.org/2025/05/08/gsoc-2025-selected-projects/) associated project.
When adding a new UI test, one is faced with hundreds of subdirectories in `tests/ui` reflecting various categories. Knowing where to put the new test is not trivial, as many of the categories have slightly misleading names. For example, `moves` does not only refer to the `move` keyword but to functions taking ownership in general, whereas `allocator` does not refer to allocation in general but rather to the very specific `allocator_api` and `global_allocator` features.
Many contributors will therefore place their test at the top level of ̀`tests/ui` where it will be mixed with hundreds of unrelated tests.
This PR is a tentative move towards more clearly defined tag/categories, with a SUMMARY.md file documenting the true purpose of each subdirectory, placed inside `tests/ui`.

Let String pass #[track_caller] to its Vec calls
I've added `#[track_caller]` to `String` methods that delegate to `Vec` methods that already have `#[track_caller]`.
I've also added `#[track_caller]` to methods that have `assert!` or `panic!` due to invalid inputs.
