Do not unconditionally succeed RUSTC_WRAPPER checks when run by build scripts
rust-analyzer's RUSTC_WRAPPER unconditionally succeeds `cargo check`
invocations tripping up build scripts using `cargo check` to probe for
successful compilations. To prevent this from happening the RUSTC_WRAPPER
now checks if it's run from a build script by looking for the
`CARGO_CFG_TARGET_ARCH` env var that cargo sets only when running build
scripts.

Auto merge of #12993 - lowr:patch/swap-name-and-escaped-name, r=Veykril
Make `Name` hold escaped name
Resolves #12787
Resolves rust-lang/rust#99361
This PR effectively swaps `Name` and `EscapedName` in hir. In other words, it makes `Name` hold and print escaped raw identifiers and introduces another struct `UnescapedName` for cases where you need to print names without "r#" prefix.
My rationale is that it makes it easier for us to format an escaped name into string, which is what we want when we serialize names in general. This is because we format a name into string usually when we are presenting it to the users and arguably they expect its escaped form as that's what they see and write in the source code.
I split the change for `Name` into 3 commits to make it easier to follow but it also made some tests fail in the intermediate commits. I can squash them into a commit after the review if desired. I've also made similar changes for `ModPath` and `EscapedModPath` as it makes them consistent with `Name`.
For reference, there was a brief discussion on this in [a zulip thread](https://rust-lang.zulipchat.com/#narrow/stream/185405-t-compiler.2Frust-analyzer/topic/escaping.20.60Name.60s).

Auto merge of #12942 - lowr:fix/concat-with-char, r=Veykril
fix: make `concat!` work with char
Fixes #12921
- I avoided making `unquote_str()` take char literals as well because it's depended on by another function `parse_string()` that's only supposed to take strings.
- Even with this patch, we don't output `\0` as `\u{0}` which #12921 pointed out ~~, but we're not actually responsible for serializing it but rowan is~~. They are functionally equivalent and I don't think it'd cause any confusion, but we *could* try escaping them before serialization (for reference, `rustc -Zunpretty=expanded`, which `cargo expand` uses under the hood, [makes use of `str::escape_default()`](https://github.com/rust-lang/rust/blob/3830ecaa8db798d2727cbdfa4ddf314ff938f268/compiler/rustc_ast/src/util/literal.rs#L161).

After some investigation it seemed that [`cmd!`](https://github.com/rust-lang/rust-analyzer/blob/51705698bd66919435e4fcbc25d96bd7fc5583f4/crates/sourcegen/src/lib.rs#L139) didn't execute the expected (stable) rustfmt.
A simple `xshell` test failed too:
```rust
use xshell::{cmd, Shell};
fn main() {
let sh = &Shell::new().unwrap();
sh.set_var("RUSTUP_TOOLCHAIN", "stable");
let version = cmd!(sh, "rustfmt --version").read().unwrap_or_default();
println!("{version}");
}
```
Bypassing `xshell` and using `Command` directly failed too:
```rust
use std::process::{Command, Stdio};
fn main() {
let child = Command::new("rustfmt")
.arg("--version")
.stdin(Stdio::null())
.stdout(Stdio::piped())
.env("RUSTUP_TOOLCHAIN", "stable")
.spawn()
.expect("failed to start");
let output = child.wait_with_output().unwrap();
let version = String::from_utf8_lossy(&output.stdout);
println!("{version}");
}
```
Spawning `cargo +stable fmt version` [failed too](https://github.com/rust-lang/rustup/issues/3036) with `error: no such subcommand: +stable`.
Only `rustup run stable` worked fine for both `cargo` and `fmt`.

Add more constructors and entry-APIs for la-arena
`la-arena` on crates.io is quite helpful when just a thin wrapper for Vec with u32 indices is needed.
But the current API is not ergonomic enough.
This PR
- Adds `ArenaMap::new`. Not sure why only `Arena` has it now.
- Adds `Arena{,Map}::with_capacity` for known-size storage.
- Adds entry-API for `ArenaMap` for easier `.entry(idx).or_default().push(value)` or `.entry(idx).or_insert(...)` operations.

Don't switch workspace on vfs file changes from libraries
When r-a starts up, it starts switching the workspace before all vfs

times until all vfs changes have been processed. This scales with the
size of the project and its dependencies. If workspace files from
dependencies as well as the sysroot get loaded, we shouldn't switch
the workspace as those have no impact on the project workspace.

There is still the problem that all the diagnostics are cleared, only clearing diagnostics of the relevant workspace isn't easily doable though I think, will have to dig into that

I've split the implementation out into 4 steps to make code review easier:
