[red-knot] Fix Leaking Narrowing Constraint in ast::ExprIf (#14590)
## Summary

Closes #14588


```py
x: Literal[42, "hello"] = 42 if bool_instance() else "hello"
reveal_type(x)  # revealed: Literal[42] | Literal["hello"]

_ = ... if isinstance(x, str) else ...

# The `isinstance` test incorrectly narrows the type of `x`.
# As a result, `x` is revealed as Literal["hello"], but it should remain Literal[42, "hello"].
reveal_type(x)  # revealed: Literal["hello"]
```

## Test Plan
mdtest included!

## Summary

This is just a small refactor to remove the `FormatFStringPart` as it's
only used in the case when the f-string is not implicitly concatenated
in which case the only part is going to be `FString`. In implicitly
concatenated f-strings, we use `StringLike` instead.

This PR adds a sometimes-available, safe autofix for [unraw-re-pattern
(RUF039)](https://docs.astral.sh/ruff/rules/unraw-re-pattern/#unraw-re-pattern-ruf039),
which prepends an `r` prefix. It is used only when the string in
question has no backslahses (and also does not have a `u` prefix, since
that causes a syntax error.)

Closes #14527

Notes: 
- Test fixture unchanged, but snapshot changed to include fix messages.
- This fix is automatically only available in preview since the rule
itself is in preview

[red-knot] Semantic index: handle invalid breaks (#14522)
## Summary

This fix addresses panics related to invalid syntax like the following
where a `break` statement is used in a nested definition inside a
loop:

```py
while True:

    def b():
        x: int

        break
```

closes #14342

## Test Plan

* New corpus regression tests.
* New unit test to make sure we handle nested while loops correctly.
This test is passing on `main`, but can easily fail if the
`is_inside_loop` state isn't properly saved/restored.

[red-knot] PEP 695 type aliases (#14357)
## Summary

Add support for (non-generic) type aliases. The main motivation behind
this was to get rid of panics involving expressions in (generic) type
aliases. But it turned out the best way to fix it was to implement
(partial) support for type aliases.

```py
type IntOrStr = int | str

reveal_type(IntOrStr)  # revealed: typing.TypeAliasType
reveal_type(IntOrStr.__name__)  # revealed: Literal["IntOrStr"]

x: IntOrStr = 1

reveal_type(x)  # revealed: Literal[1]

def f() -> None:
    reveal_type(x)  # revealed: int | str
```

## Test Plan

- Updated corpus test allow list to reflect that we don't panic anymore.
- Added Markdown-based test for type aliases (`type_alias.md`)

## Summary

Adds meta information to `Type::Todo`, allowing developers to easily
trace back the origin of a particular `@Todo` type they encounter.

Instead of `Type::Todo`, we now write either `type_todo!()` which
creates a `@Todo[path/to/source.rs:123]` type with file and line
information, or using `type_todo!("PEP 604 unions not supported")`,
which creates a variant with a custom message.

`Type::Todo` now contains a `TodoType` field. In release mode, this is
just a zero-sized struct, in order not to create any overhead. In debug
mode, this is an `enum` that contains the meta information.

`Type` implements `Copy`, which means that `TodoType` also needs to be
copyable. This limits the design space. We could intern `TodoType`, but
I discarded this option, as it would require us to have access to the
salsa DB everywhere we want to use `Type::Todo`. And it would have made
the macro invocations less ergonomic (requiring us to pass `db`).

So for now, the meta information is simply a `&'static str` / `u32` for
the file/line variant, or a `&'static str` for the custom message.
Anything involving a chain/backtrace of several `@Todo`s or similar is
therefore currently not implemented. Also because we currently don't see
any direct use cases for this, and because all of this will eventually
go away.

Note that the size of `Type` increases from 16 to 24 bytes, but only in
debug mode.

## Test Plan

- Observed the changes in Markdown tests.
- Added custom messages for all `Type::Todo`s that were revealed in the
tests
- Ran red knot in release and debug mode on the following Python file:
  ```py
  def f(x: int) -> int:
      reveal_type(x)
  ```
Prints `@Todo` in release mode and `@Todo(function parameter type)` in
debug mode.

We should probably get rid of this entirely and subsume it's
functionality in the normal ecosystem checks? I don't think we're using
the black comparison tests anymore, but maybe someone wants it?

There are a few major parts to this:

1. Making the formatter script idempotent, so it can be run repeatedly
and is robust to changing commits
2. Reducing the overhead of the git operations, minimizing the data
transfer
3. Parallelizing all the git operations by repository

This reduces the setup time from 80s to 16s (locally).

The initial motivation for idempotency was to include the repositories
in the GitHub Actions cache. I'm not sure it's worth it yet — they're
about 1GB and would consume our limited cache space. Regardless, it
improves correctness for local invocations.

The total runtime of the job is reduced from ~4m to ~3m.

I also made some cosmetic changes to the output paths and such.
