Move `unnecessary_unsafety_doc` to `pedantic`
This lint was added in #9822. I like the idea, but also agree with #9986 as well. I think it should at least not be warn-by-default. This is one of these cases, where I'd like a group between pedantic and restriction. But I believe that users using `#![warn(clippy::pedantic)]` will know how to enable the lint if they disagree with it.

Since the lint is new:
changelog: none
r? `@flip1995` since I'd suggest back porting this, the original PR was merged 16 days ago.
Closes: #9986 (While it doesn't address everything, I believe that this is the best compromise)
Move `index_refutable_slice` to `pedantic`
During the creation, I out this lint into the nursery group to let it run in the wild before moving it to a commonly used group. This move never happened until now, though. It should be safe, as Clippy and I have been using it for months and there are no open issues for is :)

Add allow-mixed-uninlined-format-args config
Implement `allow-mixed-uninlined-format-args` config param to change the behavior of the `uninlined_format_args` lint. Now it is a part of `style` per [Zulip chat](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/.60uninlined_format_args.60.20category), and won't propose inlining in case of a mixed usage, e.g. `print!("{} {}", var, 1+2)`. If the user sets `allow-mixed-uninlined-format-args` config param to `false`, the lint would behave like it did before -- proposing to inline args even in the mixed case.

Separate lifetime ident from lifetime resolution in HIR
Drive-by: change how suggested generic args are computed.

I recommend reviewing commit-by-commit.
Make rustc_target usable outside of rustc
I'm working on showing type size in rust-analyzer (https://github.com/rust-lang/rust-analyzer/pull/13490) and I currently copied rustc code inside rust-analyzer, which works, but is bad. With this change, I would become able to use `rustc_target` and `rustc_index` directly in r-a, reducing the amount of copy needed.
This PR contains some feature flag to put nightly features behind them to make crates buildable on the stable compiler + makes layout related types generic over index type + removes interning of nested layouts.
Avoid `GenFuture` shim when compiling async constructs
Previously, async constructs would be lowered to "normal" generators, with an additional `from_generator` / `GenFuture` shim in between to convert from `Generator` to `Future`.
The compiler will now special-case these generators internally so that async constructs will *directly* implement `Future` without the need to go through the `from_generator` / `GenFuture` shim.
The primary motivation for this change was hiding this implementation detail in stack traces and debuginfo, but it can in theory also help the optimizer as there is less abstractions to see through.

Given this demo code:
```rust
pub async fn a(arg: u32) -> Backtrace {
let bt = b().await;
let _arg = arg;
bt
}
pub async fn b() -> Backtrace {
Backtrace::force_capture()
}
```
I would get the following with the latest stable compiler (on Windows):
```
4: async_codegen:🅱️:async_fn$0
at .\src\lib.rs:10
5: core::future::from_generator::impl$1::poll<enum2$<async_codegen:🅱️:async_fn_env$0> >

```
whereas now I get a much cleaner stack trace:
```
3: async_codegen:🅱️:async_fn$0
at .\src\lib.rs:10
4: async_codegen:🅰️:async_fn$0
at .\src\lib.rs:4
