Use the new solver in the `impossible_predicates`
The old solver is unsound for many reasons. One of which was weaponized by `@lcnr` in #140212, where the old solver was incompletely considering a dyn vtable method to be impossible and replacing its vtable entry with a null value. This null function could be called post-mono.
The new solver is expected to be less incomplete due to its correct handling of higher-ranked aliases in relate. This PR switches the `impossible_predicates` query to use the new solver, which patches this UB.

The current use of `RustfmtState` doesn't serve its main purpose as it
never does the lazy evaulation since `Build::build` forces it to be ready
on the early stage. If we want rustfmt to be ready on the early stage, we
don't need to have `RustfmtState` complexity at all.

Placeholders are still given for the content of the whole block. However, if the
result of the original `if let` or `match` expression was assigned, the
assignment is reflected in the suggestion.
No-op assignments (`let x = x;`) are skipped though, unless they contain an
explicit type which might help the compiler (`let x: u32 = x;` is kept).
Currently, the code for process aborts is duplicated across `panic_abort` and `std`. This PR uses `#[rustc_std_internal_symbol]` to make the `std` implementation available to `panic_abort` via the linker, thereby deduplicating the code.
Temporarily use Windows Server 2022 instead of Windows Server 2025 images
Tracking issue: https://github.com/rust-lang/rust/issues/141022
At the moment, it seems like Windows Server 2025 20250504.1.0 is misconfigured, causing insufficient disk space failures. Temporarily go back to Windows Server 2022 in the hope that those are not also misconfigured to try to unblock the queue.

Unfortunately, multiple people are reporting linker warnings related to
`__rust_no_alloc_shim_is_unstable` after this change. The solution isn't
quite clear yet, let's revert to green for now, and try a reland with a
determined solution for `__rust_no_alloc_shim_is_unstable`.
This reverts commit c8b7f32434, reversing
changes made to 667247db71.

This updates some doctests that fail to run on android. We will soon be
supporting cross-compiled doctests, and the `arm-android` job fails to
run these tests.
In summary:
- Android re-exports some traits from linux under a different path.
- Android doesn't seem to have common unix utilities like `true`,
`false`, or `whoami`, so these are disabled.
