9321: Inline generics in const and function trait completions r=Veykril a=RDambrosio016
This PR does a couple of things:
- moves path_transform from ide_assists to ide_db to be shared by both assists and completions
- when completing a const or a function for a trait, it will "inline" any generics in those associated items instead
of leaving the generic's name. For example:
```rust
trait Foo<T> {
const BAR: T;
fn foo() -> T;
}
struct Bar;
impl Foo<u32> for Bar {
// autocompletes to this
fn foo() -> u32;
// and not this (old)
fn foo() -> T;
// also works for associated consts and where clauses
const BAR: u32 = /* */
}
```
Currently this does not work for const generics, because `PathTransform` does not seem to account for them. If this should work on const generics too, `PathTransform` will need to be changed. However, it is uncommon to implement a trait only for a single const value, so this isnt a huge concern.

9108: Don't show extract into variable assist for unit expressions r=jonas-schievink a=brandondong
**Reproduction:**
```rust
fn main() {
let mut i = 3;
$0if i >= 0 {
i += 1;
} else {
i -= 1;
}$0
}
```
1. Select the snippet of code between the $0's.
2. The extract into variable assist shows up, pushing down the more useful extract into function assist.
3. The resulting output of selecting the extract into variable assist is valid but with the extracted variable having the unit type:
```rust
fn main() {
let mut i = 3;
let var_name = if i >= 0 {
i += 1;
} else {
i -= 1;
};
var_name
}
```
**Fix:**
- Don't show the extract into variable assist for unit expressions. I could not think of any scenarios where such a variable extraction would be desired.

Fixes#9100Fixes#9099
Kind of fixes #9109, it now copies all the generics might be incorrect if the variant doesn't use all of them)
