9804: Generate method from call r=matklad a=mahdi-frms
Needs a bit of refactoring. Tests also should be added.

9825: Generate default impl when converting #[derive(Default)] to manual impl r=Veykril a=yoshuawuyts
Similar to https://github.com/rust-analyzer/rust-analyzer/pull/9814, but for `#[derive(Default)]`. Thanks!
## Follow-up steps
I've added the tests inside `handlers/replace_derive_with_manual_impl.rs` again, but I'm planning a follow-up PR to extract these to `utils/` so we can share them between assists - and maybe even add another assist just for the purpose of testing these impls (e.g. `generate_default_trait_body`).
The step after _that_ is likely to fill out the remaining traits, so we can make it so whenever RA auto-completes a trait which also can be derived, we provide a default function body.

9814: Generate default impl when converting `#[derive(Debug)]` to manual impl r=yoshuawuyts a=yoshuawuyts
This patch makes it so when you convert `#[derive(Debug)]` to a manual impl, a default body is provided that's equivalent to the original output of `#[derive(Debug)]`. This should make it drastically easier to write custom `Debug` impls, especially when all you want to do is quickly omit a single field which is `!Debug`.
This is implemented for enums, record structs, tuple structs, empty structs - and it sets us up to implement variations on this in the future for other traits (like `PartialEq` and `Hash`).
Thanks!
## Codegen diff
This is the difference in codegen for record structs with this patch:
```diff
struct Foo {
bar: String,
}
impl fmt::Debug for Foo {
fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
- todo!();
+ f.debug_struct("Foo").field("bar", &self.bar).finish()
}
}
```
