5971: Implement async blocks r=flodiebold a=oxalica
Fix#4018
@flodiebold already gave a generic guide in the issue. Here's some concern about implementation detail:
- Chalk doesn't support generator type yet.
- Adding generator type as a brand new type (ctor) can be complex and need to *re-introduced* builtin impls. (Like how we implement closures before native closure support of chalk, which is already removed in #5401 )
- The output type of async block should be known after type inference of the whole body.
- We cannot directly get the type from source like return-positon-impl-trait. But we still need to provide trait bounds when chalk asking for `opaque_ty_data`.
- During the inference, the output type of async block can be temporary unknown and participate the later inference.
`let a = async { None }; let _: i32 = a.await.unwrap();`
So in this PR, the type of async blocks is inferred as an opaque type parameterized by the `Future::Output` type it should be, like what we do with closure type.
And it really works now.
Well, I still have some questions:
- The bounds `AsyncBlockImplType<T>: Future<Output = T>` is currently generated in `opaque_ty_data`. I'm not sure if we should put this code here.
- Type of async block is now rendered as `impl Future<Output = OutputType>`. Do we need to special display to hint that it's a async block? Note that closure type has its special format, instead of `impl Fn(..) -> ..` or function type.

5981: Properly preserve macro braces during dbg! removal r=jonas-schievink a=SomeoneToIgnore
Do `dbg![2 + 2] * 5` -> `(2 + 2) * 5`
This PR also implicitly handles the `{}` case too, but I decided not to add it into the test case since it's a compiler error on the latest stable rustc.

5955: Remove merge import code duplication r=jonas-schievink a=Veykril
This removes the code duplication caused by #5935, this also allows the assist to merge imports that have equal visibility and prevents merges of unequal visibility. This PR also fixes an iteration mistake in the mentioned PR:
Turns out I made a mistake when writing the `segment_iter` function, I was assuming that the `children` of a path will just be the segments, which is obviously not the case. This also brings insertion order of shorter paths in line with how `rustfmt` orders them.

5951: Rename record_field_pat to record_pat_field r=jonas-schievink a=pksunkara
The token was renamed but not this.
5975: Report better errors in project.json/sysroot r=jonas-schievink a=jonas-schievink
This does a bunch of light refactoring so that the `Sysroot` is loaded later, which makes sure that any errors are reported to the user. I then added a check that reports an error if libcore is missing in the loaded sysroot. Since a sysroot without libcore is very useless, this indicates a configuration error.

5956: Highlight errors in macros r=jonas-schievink a=popzxc
Resolves#4924
This PR makes rust-analyzer highlight not only the source place when error originates in macro, but also the exact places in macro which caused an error.
This is done by creating an inverse diagnostic, which points to the macro and cross-references the source place.
