Delegation: support coercion for target expression

(solves rust-lang#118212 (comment))

The implementation consist of 2 parts. Firstly, method call is generated instead of fully qualified call in AST->HIR lowering if there were no generic arguments or `Qpath` were provided. These restrictions are imposed due to the loss of information after desugaring. For example in

```rust
trait Trait {
  fn foo(&self) {}
}

reuse <u8 as Trait>::foo;
```

We would like to generate such a code:

```rust
fn foo<u8: Trait>(x: &u8) {
  x.foo(x)
}
```

however, the signature is inherited during HIR analysis where `u8` was discarded.

Then, we probe the single pre-resolved method.

P.S In the future, we would like to avoid restrictions on the callee path by `Self` autoref/autoderef in fully qualified calls, but at the moment it didn't work out.
