Support multiple targets for checkOnSave (in conjunction with cargo 1.64.0+)
This PR adds support for the ability to pass multiple `--target` flags when using
`cargo` 1.64.0+.
## Questions
I needed to change the type of two configurations options, but I did not plurialize the names to
avoid too much churn, should I ?

## Example
To see it working, on a macOS machine:
```sh
$ cd /tmp
$ cargo new cargo-multiple-targets-support-ra-test
$ cd !$
$ mkdir .cargo
$ echo '
[build]
target = [
"aarch64-apple-darwin",
"x86_64-apple-darwin",
]
' > .cargo/config.toml
$ echo '
fn main() {
#[cfg(all(target_arch = "aarch64", target_os = "macos"))]
{
let a = std::fs::read_to_string("/tmp/test-read");
}
#[cfg(all(target_arch = "x86_64", target_os = "macos"))]
{
let a = std::fs::read_to_string("/tmp/test-read");
}
#[cfg(all(target_arch = "x86_64", target_os = "windows"))]
{
let a = std::fs::read_to_string("/tmp/test-read");
}
}

Helps with #13282
fix: format expression parsing edge-cases
- Handle positional arguments with formatting options (i.e. `{:b}`). Previously copied `:b` as an argument, producing broken code.
- Handle indexed positional arguments (`{0}`) ([reference](https://doc.rust-lang.org/std/fmt/#positional-parameters)). Previously copied over `0` as an argument.
Note: the assist also breaks when named arguments are used (`"{name}$0", name = 2 + 2` is converted to `"{}"$0, name`. I'm working on fix for that as well.
Update several crates to bring support for the new Tier 3 Windows tar…
`cargo t` has passed on Windows 11 with both `x86_64-pc-windows-gnu` and `x86_64-pc-windows-gnullvm` targets.
fix: check visibility of each path segment
Upon path resolution, we have not been checking if every def pointed to by each segment of the path is visible from the original module. This leads to incorrect import resolutions, in particular when one uses glob imports and names collide.
There is decent amount of changes in this PR because:
- some of our tests were not correct in terms of visibility
- I left several basic nameres tests as-is (with expect test updated) since I thought it would be nice to ensure we don't resolve defs that are not visible.
- `fix_visibility` assist relied on `Semantics::resolve_path()`, which uses the name resolution procedure I'm fixing and wouldn't be able to "see through" the items with strict visibility with this patch
The first commit is the gist of the fix itself.

Fix `tt::Punct`'s spacing calculation
Fixes#13499
We currently set a `tt::Punct`'s spacing to `Spacing::Joint` unless its next token is a trivia (i.e. whitespaces or comment). As I understand it, rustc only [sets `Spacing::Joint` if the next token is an operator](5b3e909075/compiler/rustc_parse/src/lexer/tokentrees.rs (L77-L78)) and we should follow it to guarantee the consistent behavior of proc macros.
Fix the length displayed for byte string literals with escaped newlines
This is a fix for the problem I reported earlier: "the length of byte strings containing escaped newlines is displayed two bytes longer when the first escaped character is a newline".
I would appreciate it if you could review the fix.
Many thanks.
Closes#13567
