Auto merge of #11373 - Red-Rapious:master, r=blyxyas,y21

Added new lint: `reserve_after_initialization`

Closes https://github.com/rust-lang/rust-clippy/issues/11330.

A new lint that informs the user about a more concise way to create a vector with a known capacity.
Example:
```rust
let mut v: Vec<usize> = vec![];
v.reserve(10);
```

Produces the following help:
```rust
  |
2 | /     let mut v: Vec<usize> = vec![];
3 | |     v.reserve(10);
  | |__________________^ help: consider using `Vec::with_capacity(space_hint)`: `let v: Vec<usize> = Vec::with_capacity(10);`
  |
```

And can be rewritten as:
```rust
let v: Vec<usize> = Vec::with_capacity(10);
```
