6154: Shorten type hints for std::iter Iterators r=SomeoneToIgnore a=Veykril
Fixes#3750.
This re-exports the `hir_expand::name::known` module to be able to fetch the `Iterator` and `iter` names.
I'm not sure if there is anything to do with `Solution::Ambig` in `normalize_trait_assoc_type` or whether discarding those results is always wanted.

Percentage is a UI concern, the physical fact here is fraction. It's
sad that percentage bleeds into the protocol level, we even duplicated
this bad API ourselves!
6158: Fix for negative literals in macros r=matklad a=cutsoy
_This pull request fixes #6028._
When writing `-42.0f32` in Rust, it is usually parsed as two different tokens (a minus operator and a float literal).
But a procedural macro can also generate new tokens, including negative [float literals](https://doc.rust-lang.org/stable/proc_macro/struct.Literal.html#method.f32_suffixed):
```rust
#[proc_macro]
fn example_verbose(input: TokenStream) -> TokenStream {
let literal = Literal::f32_suffixed(-42.0);
quote! { #literal }
}
```
or even shorter
```rust
#[proc_macro]
fn example(input: TokenStream) -> TokenStream {
let literal = -42.0f32;
quote! { #literal }
}
```
Unfortunately, these currently cause RA to crash:
```
thread '<unnamed>' panicked at 'Fail to convert given literal Literal {
text: "-42.0f32",
id: TokenId(
4294967295,
),
}', crates/mbe/src/subtree_source.rs:161:28
```
This pull request contains both a fix 8cf9362 and a unit test 27798ee. In addition, I installed the patched server with `cargo xtask install --server` and verified in VSCode that it no longer crashes when a procedural macro returns a negative number literal.

* Chalk very recently (like an hour ago) merged a fix that prevents rust analyzer from panicking. This allows it to be usable again for code that hits those situations. See #6134, #6145, Probably #6120
6124: Better normalized crate name usage r=jonas-schievink a=SomeoneToIgnore
Closes https://github.com/rust-analyzer/rust-analyzer/issues/5343
Closes https://github.com/rust-analyzer/rust-analyzer/issues/5932
Uses normalized name for code snippets (to be able to test the fix), hover messages and documentation rewrite links (are there any tests for those?).
Also renamed the field to better resemble the semantics.

6139: Make find_path_prefixed configurable r=matklad a=Veykril
This makes `find_path_prefixed` more configurable allowing one to choose whether it always returns absolute paths, self-prefixed paths or to ignore local imports when building the path.
The config names are just thrown in here, taking better names if they exist :)
This should fix#6131 as well?

6147: Do not leave braces for colons in dbg! r=matklad a=SomeoneToIgnore
Tweak remove dbg heuristics a bit to remove braces when colons (`:`) are used in the non-leaf dbg expressions.
Before:
`dbg!(Foo::foo_test()).bar()` -> `(Foo::foo_test()).bar()`
After:
`dbg!(Foo::foo_test()).bar()` -> `Foo::foo_test().bar()`

6111: Add assist for converting the base of integer literals. r=SomeoneToIgnore a=vlakreeh
This PR adds an assist similar to Intellij's [convert number to](https://i.imgur.com/JH6wstP.png). It also does a small refactor to [assists/src/tests.rs](fc34403018/crates/assists/src/tests.rs) to add the ability to specify the resolved assist for a specific action within an assist group.
## Demo
