Fills in server information.
Derives CodeAction capabilities from the client. If code action literals
are unsupported we fall back to the "simple support" which just sends back
commands (this is already supported in our config). The difference being
that we did not adjust our server capabilities so that if the client was
checking for `CodeActionProvider: "true"` in the response that would have failed.
4501: Querify `importable_locations_in_crate` r=jonas-schievink a=jonas-schievink
This brings the time needed to compute the `add_missing_impl_members` assist down from ~5 minutes to 20 seconds on my test workload (which is editing within an impl of a MIR [`MutVisitor`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/mir/visit/trait.MutVisitor.html))

4497: Create LowerCtx on the fly r=matklad a=edwin0cheng
Previously we create `LowerCtx` at the beginning of lowering, however, the hygiene content is in fact changing between macro expression expanding.
This PR change it to create the `LowerCtx` on the fly to fix above bug.
However, #4465 is not fixed by this PR, the goto-def is still not work yet. It only fixed the infer part.

4493: Provide builtin impls of Fn traits for fn-pointers r=flodiebold a=hban
Meant to be, but isn't actually a fix for #2880.
Consider this snippet:
```rust
use std::marker::PhantomData;
use std::ops::Deref;
struct Lazy<T, F/* = fn() -> T*/>(F, PhantomData<T>);
impl<T, F> Lazy<T, F> {
pub fn new(f: F) -> Lazy<T, F> {
Lazy(f, PhantomData)
}
}
impl<T, F: FnOnce() -> T> Deref for Lazy<T, F> {
type Target = T;
fn deref(&self) -> &T { todo!() }
}
fn test() {
let lazy1: Lazy<u32, _> = Lazy::new(|| 0u32);
let r1 = lazy1.to_string();
fn make_u32_fn() -> u32 { todo!() }
let make_u32_fn_ptr: fn() -> u32 = make_u32_fn;
let lazy2: Lazy<u32, _> = Lazy::new(make_u32_fn_ptr);
let r2 = lazy2.to_string();
}
```
* On current master:
* When type default is commented-out, `r1` is correctly inferred, `r2` in _{unknown}_.
* When type default is not commented-out, both `r1` and `r2` are _{unknown}_.
* With this PR:
* When type default is commented-out, both `r1` and `r2` are correctly inferred.
* When type default is not commented-out, both `r1` and `r2` are _{unknown}_.
Well, it's a improvement at least. I guess this thing with type defaults is a different problem.
I also tried add Fn impls for fn items, but wasn't successful. So this PR only adds those impls for fn pointers.

4499: CodeLens configuration options r=vsrs a=vsrs
This PR
- adds an option to granularly enable\disable all CodeLens, just like the TypeScript extension.
- fixes a minor bug for doctests. It makes no sense to show `Debug` lens for them as cargo `Can't skip running doc tests with --no-run`.

4489: Memory allocation optimization r=matklad a=simonvandel
I did some profiling using DHAT, and this was what I could easily optimize without much knowledge of the codebase.
This speeds up analysis-stats on rust-analyser by ~4% on my local machine.

4484: Allow calling dyn trait super trait methods without the super trait in scope r=flodiebold a=flodiebold
This also removes some vestiges of the old impl trait support which I think aren't currently in use.

4479: Chalk upgrade r=matklad a=flodiebold
This includes the fix for `dyn Trait` super traits, but I noticed that still a lot of `db.super_trait_method()` calls don't work because the super trait isn't in scope (because it doesn't actually need to be). Somehow, I thought we handled that already, but I'll fix it in a separate PR. Also I'll see what happens if we use more of Chalk's new built-in types and traits in a separate PR.

4288: Add rename self to parameter and back. r=zbsz a=zbsz
This is a first stab at #3439
I liked the idea to do this as a rename instead of separate assist, so I tried implementing that.
It mostly works, but I'm sure there are some cases that I missed, especially in regards to parameter type.
Note: I'm playing with this this as a way to learn Rust and this project. So I'm sure it could be cleaner and put in better places`. Any suggestions?
