Only produce .xz tarballs on CI
This PR adds a `./configure` option to choose which tarball compression formats to produce, and changes our CI configuration to only produce `.xz` tarballs. The release process will then recompress everything into `.gz` when producing a release.
This will drastically reduce our storage costs for CI artifacts, as we'd stop storing the same data twice. **Stable, beta and nightly releases will not be affected by this at all.**
Before landing this we'll need to increase the VM size of our release process, to recompress everything in a reasonable amount of time.

Don't give an error when creating a file for the first time
Previously, `os.remove` would always give a FileNotFound error the first
time you called it, causing bootstrap to make unnecessary copies. This
now only calls `remove()` if the file exists, avoiding the unnecessary
error.
This is a pretty small cleanup but I think it's useful. Taken from https://github.com/rust-lang/rust/pull/79540.

This is a rebase of #75784. I'm hoping to push this past the finish line!

refactor: removing library/alloc/src/vec/mod.rs ignore-tidy-filelength
This PR removes the need for ignore-tidy-filelength for library/alloc/src/vec/mod.rs which is part of the issue #60302
It is probably easiest to review this PR by looking at it commit by commit rather than looking at the overall diff.

remove empty wraps, don't return Results from from infallible functions
This makes code easier to understand because it is more obvious when a function actually can't fail (return Err or None)
Make functions that only ever return Some(x), return x directly
Remove return type from functions that return Option<(), Err> but would only ever return Ok(()).

Revert "Cleanup markdown span handling"
Reverts rust-lang/rust#80244. This caused a diagnostic regression, originally it was:
```
warning: unresolved link to `std::process::Comman`
--> link.rs:3:10
|
3 | //! [a]: std::process::Comman
| ^^^^^^^^^^^^^^^^^^^^ no item named `Comman` in module `process`
|
= note: `#[warn(broken_intra_doc_links)]` on by default
```
but after that PR rustdoc now displays
```
warning: unresolved link to `std::process::Comman`
--> link.rs:1:14
|
1 | //! Links to [a] [link][a]
| ^^^ no item named `Comman` in module `process`
|
= note: `#[warn(broken_intra_doc_links)]` on by default
```
which IMO is much less clear.

Improvements to NatVis support
NatVis files describe how to display types in some Windows debuggers,
such as Visual Studio, WinDbg, and VS Code.
This commit makes several improvements:
* Adds visualizers for Rc<T>, Weak<T>, and Arc<T>.
* Changes [size] to [len], for consistency with the Rust API.
Visualizers often use [size] to mirror the size() method on C++ STL
collections.
* Several visualizers used the PVOID and ULONG typedefs. These are part
of the Windows API; they are not guaranteed to always be defined in a
pure Rust DLL/EXE. I converted PVOID to `void*` and `ULONG` to
`unsigned long`.
* Cosmetic change: Removed {} braces around the visualized display
for `Option` types. They now display simply as `Some(value)` or
`None`, which reflects what is written in source code.
* The visualizer for `alloc::string::String` makes assumptions about
the layout of `String` (it casts `String*` to another type), rather
than using symbolic expressions. This commit changes the visualizer
so that it simply uses symbolic expressions to access the string
data and string length.
* The visualizers for `str` and `String` now place the character data
array under a synthetic `[chars]` node. When expanding a `String`
node, users rarely want to see an array of characters. This just places
them behind one expansion node / level.

Lint on redundant trailing semicolon after item
We now lint on code like this:
```rust

fn foo() {};
struct Bar {};

Previously, this caused warnings in Cargo, so it was disabled.

[rustdoc] Box ItemKind to reduce the size of `Item`
This brings the size of `Item` from
```
[src/librustdoc/lib.rs:103] std::mem::size_of::<Item>() = 536
```
to
```
[src/librustdoc/lib.rs:103] std::mem::size_of::<Item>() = 136
```
This is an alternative to https://github.com/rust-lang/rust/pull/79967; I don't think it makes sense to make both changes.
Helps with #79103.

bootstrap: put the component name in the tarball temp dir path
