Update the arm-* and aarch64-* platform docs.
This PR updates some of the arm*-unknown-none target docs, and adds some missing target pages.
## aarch64-none-elf and aarch64-none-elf-softfloat
The Rust Embedded Devices Working Group's Arm Team is added as a maintainer, and a target page is added. Links are added to the EDWG's support crates for this target.
## armv7a-none-eabi and armv7a-none-eabihf
The Rust Embedded Devices Working Group's Arm Team is added as a maintainer, and a target page is added. Links are added to the EDWG's support crates for this target.
## armv7r-none-eabi and armv7r-none-eabihf
The Rust Embedded Devices Working Group's Arm Team is added as a maintainer, and the target page is split from the Big Endian versions. Links are added to the EDWG's support crates for this target.
## armebv7r-none-eabi and armveb7r-none-eabihf
The target page is split from the Little Endian versions. No change in maintainers.
I have agreement to add EDWG/T-Arm as maintainers, which was voted upon in [their repo](https://github.com/rust-embedded/wg/issues/851).
This is important to note, as it affects how easy it is to build a
binary, and that `#![no_std]` is mandatory.
A different PR should probably add this to all the other platform pages.
Make `AssocItem` aware of its impl kind
The general goal is to have fewer query dependencies by making `AssocItem` aware of its parent impl kind (inherent vs. trait) without having to query the parent def_kind.

bootstrap: rustdoc-js tests can now be filtered by js files
Before, a command like `./x test tests/rustdoc-js/path-ordering.js` would succeed, but run no tests, since the names of the tests are based on the `.rs` file. This is a bit confusing, as the `rustdoc-js-std` test suite only has `.js` files, and thus those are the files you filter on. Now, `./x test tests/rustdoc-js/path-ordering.js` will be treated as an alias for `./x test tests/rustdoc-js/path-ordering.rs`. This is fairly simple as each `rustdoc-js` test has 2 files, 1 js file and one rust file, each with an identical base filename, so all we need to do is swap the extension.

Add --print target-spec-json-schema
This schema is helpful for people writing custom target spec JSON. It can provide autocomplete in the editor, and also serves as documentation when there are documentation comments on the structs, as `schemars` will put them in the schema.
I was motivated to do this because I saw someone write their own version of this schema by hand, so demand for this clearly exists. It's not a lot of effort to implement, so I thought it would make sense.
MCP: https://github.com/rust-lang/compiler-team/issues/905
I think it would also be useful to put this in the sysroot in `etc` so people can link it directly in their editors.
I would have loved to add a test that validates the JSON schema against the spec JSON of every builtin target, but I don't want to do it as the JSON schema validation crates have incredible amounts of dependencies because JSON schema supports a ton of random features. I don't want to add that, even as a dev dependency.
Convert `no_std` and `no_core` to the new attribute infrastructure

Also added a test for these, since we didn't have any and I was kind of surprised new diagnostics didn't break anything hehe
bootstrap: Build jemalloc for LoongArch with support for 16K pages
By default, jemalloc is configured with a 4K page size. If the host’s page size is larger than this, it will crash at runtime. This patch raises the page size to 16K.
This schema is helpful for people writing custom target spec JSON. It
can provide autocomplete in the editor, and also serves as documentation
when there are documentation comments on the structs, as `schemars` will
put them in the schema.
Improve suggestion in case a bare URL is surrounded by brackets
Fixes https://github.com/rust-lang/rust/issues/146162.
With this change, output looks like this:
```

1 | //! [https://github.com]
| ^^^^^^^^^^^^^^^^^^^^ help: use an automatic link instead: `<https://github.com>`
|
= note: bare URLs are not automatically turned into clickable links
= note: `#[warn(rustdoc::bare_urls)]` on by default

Revert `assert!` desugaring changes (#122661)
Reverts rust-lang/rust#122661 to prevent rust-lang/rust#145770 slipping into beta.
cc `@estebank` (FYI)
### Review remarks
- Commit 1 is the MCVE reported in rust-lang/rust#145770 added as a regression test `tests/ui/macros/assert-desugaring-145770.rs`. Against `master`, this test fails.
- Commit 2 reverts rust-lang/rust#122661 (with a merge conflict fixed). `tests/ui/macros/assert-desugaring-145770.rs` now passes.
Update the LoongArch target documentation
This patch defines minimum CPU feature requirements, updates toolchain baseline, and streamlines maintainer list:
- Specify double-precision floating-point and LSX as mandatory CPU features
- Raise the minimum required binutils version to 2.42+, due to relocations introduced by the default medium code model
- Remove outdated maintainers to reduce irrelevant notifications

This reverts commit 1eeb8e8b15, reversing
changes made to 324bf2b9fd.
Unfortunately the assert desugaring change is not backwards compatible,
see RUST-145770.
Code such as
```rust
#[derive(Debug)]
struct F {
data: bool
}
impl std::ops::Not for F {
type Output = bool;
fn not(self) -> Self::Output { !self.data }
}
fn main() {
let f = F { data: true };
assert!(f);
}
```
would be broken by the assert desugaring change. We may need to land
the change over an edition boundary, or limit the editions that the
desugaring change impacts.
