Converts `::<_>` to an explicit type assignment.
```
let args = args.collect::<Vec<String>>();
```
->
```
let args: Vec<String> = args.collect();
```

10563: feat: Make "Generate getter" assist use semantic info r=agluszak a=agluszak
This PR makes "Generate getter" assist use semantic info instead of dealing with types encoded as strings.
Getters for types which are:
- `Copy` no longer return references
- `AsRef<str>` (i.e. `String`) return `&str` (instead of `&String`)
- `AsRef<[T]>` (i.e. `Vec<T>`) return `&[T]` (instead of `&Vec<T>`)
- `AsRef<T>` (i.e. `Box<T>`) return `&T` (instead of `&Box<T>`)
- `Option<T>` return `Option<&T>` (instead of `&Option<T>`)
- `Result<T, E>` return `Result<&T, &E>` (instead of `&Result<T, E>`)
String, Vec, Box and Option were previously handled as special cases.
Closes#10295

10543: Narrow add_missing_match_arms assist range r=Veykril a=antonfirsov
Contributes to #10220 with logic borrowed from #10267.
Note: if anyone has recommendations for further analyzers to check, I'm happy to (hard to do it on my own, I'm completely new to the language).

10491: Support nested type on replace if let with match r=k-nasa a=k-nasa
## Why
close: https://github.com/rust-analyzer/rust-analyzer/issues/8690
Now, Replacing if-let with match cant't output exhaustive patterns code.
This was because the `else` conversion used specific types (ex. Option, Result) instead of wildcards.
I thought it was more of a problem to generate non-exhaustive patterns than the benefits of using the concrete one.
How about using wildcards in `else`?
Is this change policy acceptable?
## What
- using wildcards on `make_else_arm`
- Change test cases

10546: feat: Implement promote_local_to_const assist r=Veykril a=Veykril
Fixes#7692, that is now one can invoke the `extract_variable` assist on something and then follow that up with this assist to turn it into a const.

10539: Add "generate delegate methods" assist r=Veykril a=yoshuawuyts
_Co-authored with `@rylev_.`
This patch adds a new assist: "generate delegate method" which creates a method that calls to a method defined on an inner field. Delegation is common when authoring newtypes, and having IDE support for this is the best way we can make this easier to author in Rust, bar adding language-level support for it. Thanks!
Closes#5944.
## Example
__before__
```rust
struct Age(u8);
impl Age {
fn age(&self) -> u8 {
self.0
}
}
struct Person {
ag$0e: Age,
}
```
__after__
```rust
struct Age(u8);
impl Age {
fn age(&self) -> u8 {
self.0
}
}
struct Person {
age: Age,
}
impl Person {
$0fn age(&self) -> u8 {
self.age.age()
}
}
```
