fix [`cast_possible_truncation`] offering wrong suggestion for casting float to integer
fixes: #10366

changelog: [`cast_possible_truncation`] Fix incorrect suggestions when casting from float types or to `_`
Add explanation on how to run `cargo-clippy` and `clippy-driver`
I don't know how this would be done on Windows or MacOS, feedback appreciated.
I did find this snippet for MacOS but it seems a little sketchy.

r? `@Jarcho`
Is this the best way to go about this? `unused_parens` will catch the unnecessary ones but emitting them in the first place isn't ideal
suggest `try_into` when casting to wildcard type;
fix [`cast_possible_truncation`] suggesting useless parenthesis;
remove suggesting for float to float conversion in [`cast_possible_truncation`]

docs fix: unknown field `allowed-locales`
changelog: [`DISALLOWED_SCRIPT_IDENTS`]: Replace the nonexistent `allowed-locales` in the docs with `allowed-scripts`.
Use `split-debuginfo = "unpacked"` for debug builds
On Windows this has no effect as it's unsupported. On macOS the default set by cargo is already unpacked so no effect there either
For Linux it shaves a bit off the rebuild time, for me in the case of a simple `touch` + `cargo build` it goes from 12s to 10s
It saves a good amount of disk space too, on `aarch64-unknown-linux-gnu` it saves 1.2GB for a plain `cargo build`, 3GB when also running `cargo dev` and `cargo test --no-run -F internal`

New lint: detect unnecessary struct building
Fixes#10476.
Running this lint on the top 500 crates produced one hit (in `rust-lang/rust-bindgen`) and [a PR has been submitted there](https://github.com/rust-lang/rust-bindgen/pull/2440).

`@rustbot` modify labels: rollup
Updates `interpret`, `codegen_ssa`, and `codegen_cranelift` to consume the new cast instead of the intrinsic.
Includes `CastTransmute` for custom MIR building, to be able to test the extra UB.
The lint is very slow as it doesn't cache the deeply nested check for
the attribute. If we cache it, we can reduce the time spent on checking
`rustc_borrowck` from 28s to 9s, which is a nice improvement. In the
profile, the time inside `has_sig_drop_attr` goes from 66% to 0.2%,
which is a lot more reasonable.
See the PR for nice graphs.
Do not propose to simplify a not expression coming from a macro

a general type system cleanup
removes the helper functions `traits::fully_solve_X` as they add more complexity then they are worth. It's confusing which of these helpers should be used in which context.
changes the way we deal with overflow to always add depth in `evaluate_predicates_recursively`. It may make sense to actually fully transition to not have `recursion_depth` on obligations but that's probably a bit too much for this PR.
also removes some other small - and imo unnecessary - helpers.

Really dogfood clippy
The dogfood success condition was inverted in `tests/dogfood.rs`:
```rust
assert!(!failed_packages.is_empty(), …);
```
while instead the `failed_packages` collection must be empty:
```rust
assert!(failed_packages.is_empty(), …);
```
And indeed, several clippy lint source files were not clean and had to be fixed in the process.

Use uninit checking from rustc
rustc has proper heuristics for actually checking whether a type allows being left uninitialized (by asking CTFE). We can now use this for our helper instead of rolling our own bad version with false positives.
I added this in rustc in rust-lang/rust#108669

Correct active members link in `CONTRIBUTING.md`
This corrects the link, where to find which members are currently active and can be pinged. It also adds me as the code owner of `gh-pages`. In most cases, I'm asked to review those PRs anyways :)
Otherwise, not much more to day, have a great day!

Remove box expressions from HIR
After #108516, `#[rustc_box]` is used at HIR->THIR lowering and this is no longer emitted, so it can be removed.
This is based on top of #108471 to help with conflicts, so 43490488ccacd1a822e9c621f5ed6fca99959a0b is the only relevant commit (sorry for all the duplicated pings!)
