[Debuginfo] Add MSVC Synthetic and Summary providers to LLDB
Adds handling for `tuple$<>`, `ref$<slice$2<>`, `ref$<str$>` and `enum2$<>`.
Also fixes a bug in MSVC vec/string handling where the script was unable to determine the element's type due to LLDB ignoring template arg debug information

<summary>Sample code</summary>
```rust
pub enum Number {
One = 57,
Two = 99,
}
#[repr(u8)]
pub enum Container {
First(u32),
Second { val: u64, val2: i8 },
Third,
}
...
let u8_val = b'a';
let float = 42.78000000000001;
let tuple = (u8_val, float);
let str_val = "eef";
let mut string = "freef".to_owned();
let mut_str = string.as_mut_str();
let array: [u8; 4] = [1, 2, 3, 4];
let ref_array = array.as_slice();
let mut array2: [u32; 4] = [1, 2, 3, 4];
let mut_array = array2.as_mut_slice();
let enum_val = Number::One;
let mut enum_val2 = Number::Two;
let sum_val = Container::First(15);
let sum_val_2 = Container::Second { val: 0, val2: 0 };
let sum_val_3 = Container::Third;
let non_zero = NonZeroU128::new(100).unwrap();
let large_discr = NonZeroU128::new(255);
```

Fix GDB `OsString` provider on Windows
It would throw an exception due to trying to look up `Wtf8Buf.__0`. The field it actually wants is called [`bytes`](b605c65b6e/library/std/src/sys_common/wtf8.rs (L134)).
Use python built in type annotations in LLDB visualizer scripts
Replaces type annotation comments with python's built-in type annotations.
Built-in type annotations were added in python 3.5. LLDB [currently recommends (and as of LLVM 21, will enforce)](https://github.com/llvm/llvm-project/pull/114807) a minimum python version of 3.8. Rust's test suite also requires python 3.10.
Don't use a SyntheticProvider for literally every type
Replaces a glob regex with individualized imports for each standard library type. This improves debugger performance by quite a bit when populating lots of values with lots of fields
With the glob, afaik every single value of every single type that the debugger renders is run through a python function that does quite a few string comparisons (i plan to fix those next) to determine the SyntheticProvider to use. It looks like DefaultSyntheticProvider's functions internally call the liblldb c++ functions, which ends up with identical behavior to not using a SyntheticProvider at all, except you have extra python round trips slowing things down.
These sample vidoes were run on x86-64-pc-windows-gnu. `vect` is a 1000 element `Vec<Big>`, `Big` contains a dozen or so `Small`, and `Small` contains a dozen or so `[i32; 5]`

Fix missing rustfmt in msi installer #101993
# Context
- Fixed missing `rustfmt`, `clippy`, `miri` and `rust-analyzer` in msi installer
- Fixed missing `rustfmt` for apple darwin installer
- Closes#101993
r? `@jyn514`
- Please let me know if I should request from someone else instead. I divided the changes into 3 separate commits for the ease of review. The refactoring commit `fbdfd5c03c3c979bcf105ccdd05ff4ab9f37a763` is a bit more involved, but I think it helps in the long term for readability and to avoid bugs.
- I changed `build-manifest` to `build_manifest` in order to invoke it as a library. Not sure if this is gonna break any upstream processes. I checked `generate-manifest-list` and `generate-release` but didn't find any obvious reference
- Will push fixes for linting later
Add support for automatically setting up the recommended
LSP config for Emacs.
Additionally, refactor setup.rs to make it easier to add support
for more editors in the future.
etc: Add sample rust-analyzer configs for eglot & helix
LSP configuration in editors like Emacs (eglot) and helix does not
use the same JSON format as vscode and vim do. It is not obvious
how to set up LSP for rustc in those editors and the dev guide currently
does not cover them. Adding sample configuration files for those editors
alongside the currently existing JSON one would be helpful.
I figured having those included in the repo like the JSON one might save
someone some time and frustration otherwise spent on trying to get the
more niche editors' LSP to work properly. I'll add a section in the dev
guide too.
