Add convert_named_struct_to_tuple_struct assist
Closes#11643, since the assist for converting in the other direction is already there (I based most of the implementation and all of the tests on it).
Restructure `find_path` into a separate functions for modules and non-module items
Follow up to https://github.com/rust-lang/rust-analyzer/pull/13212
Also renames `prefer_core` imports config to `prefer_no_std` and changes the behavior of no_std path searching by preferring `core` paths `over` alloc
This PR turned into a slight rewrite, so it unfortunately does a few more things that I initially planned to (including a bug fix for enum variant paths)
New assist: move_format_string_arg
The name might need some improving.
```rust
fn main() {
print!("{x + 1}");
}
```
to
```rust
fn main() {
print!("{}"$0, x + 1);
}
```
fixes#13180
ref to #5988 for similar work
* extracted `format_like`'s parser to it's own module in `ide-db`
* reworked the parser's API to be more direct
* added assist to extract expressions in format args
The name might need some improving.

feature: Assist to turn match into matches! invocation
Resolves#12510
This PR adds an assist, which convert 2-arm match that evaluates to a boolean into the equivalent matches! invocation.
fix: Only move comments when extracting a struct from an enum variant
Motivating example:
```rs
#[derive(Debug, thiserror::Error)]
enum Error {
/// Some explanation for this error
#[error("message")]
$0Woops {
code: u32
}
}
```
now becomes
```rs
/// Some explanation for this error
#[derive(Debug, thiserror::Error)]
struct Woops{
code: u32
}
#[derive(Debug, thiserror::Error)]
enum Error {
#[error("message")]
Woops(Woops)
}
```
(the `thiserror::Error` derive being copied and the struct formatting aren't ideal, though those are issues for another day)
Use correct type in "Replace turbofish with type"
And support `?` and `.await` expressions.
Fixes#13148.
The assist can still show up even if the turbofish's type is not used at all, e.g.:
```rust
fn foo<T>() {}
let v = foo::<i32>();
```
I implemented that by checking the expressions' type.
This could probably be implemented better by taking the function's return type and substituting the generic parameter with the provided turbofish, but this is more complicated.
