ensure the new solver bootstraps on CI With rust-lang#158040, the new solver should now be able to bootstrap, and this PR ensures on CI it doesn't regress. This is part of the plan in rust-lang#157780 until stabilization. This renames the job as well to something hopefully clearer, from `x86_64-gnu-pre-stabilization` to `x86_64-gnu-next-trait-solver-polonius`. And thus, also needs rust-lang/rustc-dev-guide#2904 to have the correct `doc_url`. r? kobzol

Implement `#[diagnostic::on_unknown]` for modules.
This lets you customize the error message if an item can't be found in a module. Primarily my motivation for this is that I was trying to dogfood `diagnostic::on_unknown` in my own crates and realized I was writing a lot of duplicate attributes and it'd be simpler if it just applied to things at a module level.
For example:
```rust
#[diagnostic::on_unknown(message = "oh no, `{Unresolved}` is not in module `{This}`")]
pub mod x {
pub struct Foo;
}
pub use x::Bar;
```
```
error[E0432]: oh no, `Bar` is not in module `x`
--> $DIR/on_module.rs:9:9
|
LL | pub use x::Bar;
| ^^^---
| |
| no `Bar` in `x`
|
= note: unresolved import `x::Bar`
```
Also, as shown, this implements `{Unresolved}` to reference whatever couldn't be found.
Inner attribute syntax (`#![diagnostic::on_unknown]`) is supported, however it (still) is an error to use inner tool attributes without `#![feature(custom_inner_attributes)]`.

`-Znext-solver` Emit error instead of ICE when combining {int, float} var with alias
Fixes rust-lang#158064

…risDenton std: use correct low surrogate range in Windows standard I/O code SebTardif#377 is an LLM-generated issue where the LLM managed to find a wrong constant in `std`. Low surrogates do indeed start at `0xDC00`, not `0xDCEE`. This is kind of hard to test for, maybe you have ideas Chris? r? @ChrisDenton
…isDenton std: correctly report file size on UWP Found by an LLM in SebTardif#397. UWP uses [`GetFileInformationByHandleEx`](https://learn.microsoft.com/en-us/windows/desktop/api/winbase/nf-winbase-getfileinformationbyhandleex) instead of [GetFileInformationByHandle](https://learn.microsoft.com/en-us/windows/desktop/api/fileapi/nf-fileapi-getfileinformationbyhandle), but uses the wrong field to determine file size – `EndOfFile` is a different field than `AllocationSize`. [`file_size`](https://doc.rust-lang.org/nightly/std/os/windows/fs/trait.MetadataExt.html#tymethod.file_size) should report the length of the file, not its size on disk, and only `EndOfFile` reports the former (c.f. https://learn.microsoft.com/en-us/windows/win32/api/FileAPI/nf-fileapi-setendoffile#remarks): > Each file stream has the following: > * File size: the size of the data in a file, to the byte. > * Allocation size: the size of the space that is allocated for a file on a disk, which is always an even multiple of the cluster size. > * Valid data length: the length of the data in a file that is actually written, to the byte. This value is always less than or equal to the file size. r? @ChrisDenton
