3378: vscode: redesign inlay hints to be capable of handling multiple editors for one source file r=Veetaha a=Veetaha
Fixes: #3008 (inlay corruption with multiple editors for one file).
Fixes: #3319 (unnecessary requests for inlay hints when switching unrelated source files or output/log/console windows)
Also, I don't know how, but the problem described in #3057 doesn't appear for me anymore (maybe it was some fix on the server-side, idk), the inlay hints are displaying right away. Though the last time I checked this it was caused by the server returning an empty array of hints and responding with a very big latency, I am not sure that this redesign actually fixed #3057....
We didn't handle the case when one rust source file is open in multiple editors in vscode (e.g. by manually adding another editor for the same file or by opening an inline git diff view or just any kind of preview within the same file).
The git diff preview is actually quite special because it causes memory leaks in vscode (https://github.com/microsoft/vscode/issues/91782). It is not removed from `visibleEditors` once it is closed. However, this bug doesn't affect the inlay hints anymore, because we don't issue a request and set inlay hints for each editor in isolation. Editors are grouped by their respective files and we issue requests only for files and then update all duplicate editors using the results (so we just update the decorations for already closed git diff preview read-only editors).
Also, note on a hack I had to use. `vscode.TextEdtior` identity is not actually public, its `id` field is not exposed to us. I created a dedicated upstream issue for this (https://github.com/microsoft/vscode/issues/91788).
Regarding #3319: the newly designed hints client doesn't issue requests for type hints when switching the visible editors if it has them already cached (though it does rerender things anyway, but this could be optimized in future if so wanted).

3508: Use a not so dummy implementation of env macro r=edwin0cheng a=edwin0cheng
Currently we have a dummy `env` macro implementation which expand to an empty string, such that a `include!(concat!(env!("OUT_DIR"), "/foo.rs"))` will become `include!("/foo.rs")`, and here may be a infinite loop. :)
This PR use a not so dummy version of `env` macro to prevent this infinite loop.

Allow trait autocompletions for unimplemented associated fn's, types,
and consts without using explicit keywords before hand (fn, type,
const).
The sequel to #3108.
3502: Don't reuse the Chalk solver r=matklad a=flodiebold
This slows down analysis-stats a bit (~5% in my measurement), but improves
incremental checking a lot because we can reuse trait solve results.

3499: Resolve `Self::AssocTy` in impls r=matklad a=flodiebold
To do this we need to carry around the original resolution a bit, because `Self`
gets resolved to the actual type immediately, but you're not allowed to write
the equivalent type in a projection. (I tried just comparing the projection base
type with the impl self type, but that seemed too dirty.) This is basically how
rustc does it as well.
Fixes#3249.

3494: Implement include macro r=matklad a=edwin0cheng
This PR implement builtin `include` macro.
* It does not support include as expression yet.
* It doesn't consider `env!("OUT_DIR")` yet.
