fix compiletest crash
### Motivation
When running compiler-tests locally for the `wasm32` platform, one test repeatedly crashed. It does not crash on the CI, only locally. Investigation shows that the `compiletest` itself crashes
> panicked-at-attempt-to-subtract-with-overflow
```rust
let mut head = replace(bytes, Vec::new());
let mut middle = head.split_off(HEAD_LEN);
// The following line will panic
let tail = middle.split_off(middle.len() - TAIL_LEN).into_boxed_slice();
let skipped = new_len - HEAD_LEN - TAIL_LEN;
```
### Background
The code in question collects the output of a process. Small output is kept completely, but larger output is kept only partially: the first 160 kB and the last 256 kB.
The code that performs this split crashes if the data size is less than 416 kB. There is an early out based on the "filtered" length, but it is possible that the filtered length is greater than the real length. It seems that this code was written with the assumption that the filtered length is larger than the real length, which is not true in general.
When running CI tests locally using `src/ci/docker/run.sh`, the filtered folder is `/checkout`, which is shorter than the placeholder length of 32 bytes.
### Note
This PR should not change any behaviour. It only adds an early our for a case which will definitely crash (at least if compiletest is build with integer checks).
Note that an early out makes sense here: If the real data is too small, it does not sense to split it.

ForrestOfBarnes:tests-listing-format-json-windows-fix, r=pietroalbini
Fix the tests-listing-format-json test on Windows
tests/ui/test-attrs/tests-listing-json-format.rs was failing on Windows because each path in the json-formatted output contained "\\\\" instead of "\\". `runtest::TestCx::normalize_output` already checks the compile flags for json-related arguments to handle this case, so I added an equivalent check for the new run flag.

Move `TyCtxt::mk_x` to `Ty::new_x` where applicable
Part of rust-lang/compiler-team#616
turns out there's a lot of places we construct `Ty` this is a ridiculously huge PR :S

Revert the lexing of `c"…"` string literals
Fixes \[after beta-backport\] #113235.
Further progress is tracked in #113333.
This PR *manually* reverts parts of #108801 (since a git-revert would've been too coarse-grained & messy)
and git-reverts #111647.

Specialize `try_destructure_mir_constant` for its sole user (pretty printing)
We can't remove the query, as we need to invoke it from rustc_middle, but can only implement it in mir interpretation/const eval.
r? `@RalfJung` for a first round.
While we could move all the logic into pretty printing, that would end up duplicating a bit of code with const eval, which doesn't seem great either.

Also add tests for some other shims that already behave correctly

Move `ty::ConstKind` to `rustc_type_ir`
Needed this in another PR for custom debug impls, and this will also be required to move the new solver into a separate crate that does not use `TyCtxt` so that r-a and friends can depend on the trait solver.
Rebased on top of #113325, only the second and third commits needs reviewing

This reverts commit f212ba6d6d60963c8101bb24fc3e53fca80c046f.

Remove chalk support from the compiler
Removes chalk (`-Ztrait-solver=chalk`) from the compiler and prunes any dead code resulting from this, mainly:
* Remove the chalk compatibility layer in `compiler/rustc_traits/src/chalk`
* Remove the chalk flag `-Ztrait-solver=chalk` and its `TraitEngine` implementation
* Remove `TypeWellFormedFromEnv` (and its many `bug!()` match arms)
* Remove the chalk migration mode from compiletest
* Remove the `chalkify` UI tests (do we want to keep any of these, but migrate them to `-Ztrait-solver=next`??)
Fulfills rust-lang/types-team#93.

The new version was already added to the tree as an indirect dependency
in #113046, but now our direct dependents are using it too.
