Document that `cargo clippy --fix` implies `--all-targets`
In [`cargo fix`'s documentation](https://doc.rust-lang.org/cargo/commands/cargo-fix.html) they indicate that `fix` implies `--all-targets` if no target is supplied. As Clippy uses Cargo under the hood, this also applies to Clippy, but we didn't document that behaviour.
This PR changes that

Catching, stray, commas, (I'll, never, learn, to, use, them, correctly) 😅

Don't apply `string_lit_as_bytes` if in macro expansion
The following code will emit a warning on both w! and h!, despite there being nothing the user (or library author) could do about it:
```rust
#![warn(clippy::string_lit_as_bytes)]
use windows::w;
use windows::h;
fn main() {
let _w = w!("example");
let _h = h!("example");
}
```
This is because windows-rs will create a binding `const INPUT: &[u8] = $s.as_bytes()`, and changing this to b"$s" is, well, suboptimal. I don't know enough about Rust to know if this is something that can be detected though if it can be I'm happy with closing this in favor of implementing that.
I'm not sure whether this is how it should be done though, as this simply tells clippy to not invoke this even if it's applicable (this also affects the other string lints, but didn't cause any tests to fail).

Add shortcut for Grisu3 algorithm.
While Grisu3 is way more faster for most numbers compare to Dragon4, the fall back to Dragon4 procedure for certain numbers could cause some performance regressions compare to use Dragon4 directly. Mitigating the regression caused by falling back is important for a largely used core library.
In Grisu3 algorithm implementation, there's a shortcut to jump out earlier when the fractional or integrals cannot meet the requirement of requested digits. This could significantly improve the performance of converting floating number to string as it falls back even without starting trying the algorithm.
The original idea is from the [.NET implementation](https://github.com/dotnet/runtime/blob/main/src/libraries/System.Private.CoreLib/src/System/Number.Grisu3.cs#L602-L615) and the code was originally added in [this PR](https://github.com/dotnet/coreclr/pull/14646#issuecomment-350942050). This shortcut has been shipped long time ago and has been proved working.

seems not very important to test in this detail. I could try to keep a few lines at the start around so we know what's going on (they should be fairly reliable)
configure.py: add flag for riscv{64,32}gc musl-root
Add the corresponding flag for detecting `--musl-root-riscv64gc` and `--musl-root-riscv32gc` with ./configure, which is beneficial for downstream Linux distros to create the rust package with the same "recipe" from other architectures.

[LLVM17] Adapt to `ExplicitEmulatedTLS` removal.
0d333bf0e3 removed the `ExplicitEmulatedTLS` field from `TargetOptions`.
Before that commit, `TargetMachine::useEmulatedTLS()` fell back to `TheTriple.hasDefaultEmulatedTLS()` if `ExplicitEmulatedTLS` was `false`/unset.
After that commit, `TargetMachine::useEmulatedTLS()` directly returns `Options.EmulatedTLS`, and the fallback to `TheTriple.hasDefaultEmulatedTLS()` was moved to `InitTargetOptionsFromCodeGenFlags`.
Since `rustc` does not use `InitTargetOptionsFromCodeGenFlags` (AFAICT) and instead manually builds `TargetOptions`, this PR initializes `EmulatedTLS` to `TheTriple.hasDefaultEmulatedTLS()`.
(I'm not really familiar with the details of what this option does, or if there are any tests that depend on `hasDefaultEmulatedTLS` being used correctly, so this PR is mostly untested (it does compile against LLVM17, though)).

Break up long function in trait selection error reporting + clean up nearby code
- Move blocks of code into their own functions
- Replace a few function argument types with their type aliases
- Create "AppendConstMessage" enum to replace a nested `Option`.
Check requested digit length and the fractional or integral parts of the number. Falls back earlier without trying the Grisu algorithm if the specific condition meets.
