6102: Fix MergingBehaviour::Last creating unintuitive import trees r=jonas-schievink a=Veykril
The way this behaviour currently works is actually a bit weird. Imagine the following three imports get requested for insertion in the given order:
- `winapi::um::d3d11::ID3D11Device`
- `winapi::shared::dxgiformat::DXGI_FORMAT`
- `winapi::um::d3d11::D3D11_FILTER`
After the first two you will have the following tree:
```rust
use winapi::{shared::dxgiformat::DXGI_FORMAT, um::d3d11::ID3D11Device};
```
which is to be expected as they arent nested this kind of merging is allowed, but now importing the third one will result in:
```rust
use winapi::{shared::dxgiformat::DXGI_FORMAT, um::d3d11::ID3D11Device, um::d3d11::D3D11_FILTER};
```
which is still fine according to the rules, but it looks weird(at least in my eyes) due to the long paths that are quite similar. The changes in this PR will change the criteria for when to reject `Last` merging, it still disallows multiple nesting but it also only allows single segment paths inside of the `UseTreeList`. With this change you get the following tree after the first two imports:
```rust
use winapi::um::d3d11::ID3D11Device;
use winapi::shared::dxgiformat::DXGI_FORMAT;
```
and after the third:
```rust
use winapi::shared::dxgiformat::DXGI_FORMAT;
use winapi::um::d3d11::{ID3D11Device, D3D11_FILTER};
```
Which I believe looks more like what you would expect.

6080: Add hover config `linksInHover` to suppress links r=flw-cn a=flw-cn
This PR solves the problem of using RA under vim8. It should close#6014.
Since vim8's popup-window doesn't capture focus, the URL given by RA is effectively useless. links are neither displayed correctly nor can they be clicked. This makes the hover window ugly and inefficient.
I'm providing this patch so that people who share my confusion (which I'm almost certain vim8 users do) will have a way to remove links from markdown.
I noticed that [gopls has an option](https://github.com/golang/tools/blob/master/gopls/doc/settings.md#linksinhover-bool) for a similar purpose. So I added an option `linksInHover` to enable this behavior. This is a bool value and defaults to `true` to keep the behavior consistent with the master version. But you can suppress the links in the hover text by setting it to `false`.
The name of my option, `linksInHover`, is borrowed from gopls.

6019: Remove make::path_from_text r=matklad a=Veykril
This removes the `make::path_from_text` function, which according to a note should've been private. I removed it since it didn't really serve a purpose as it was simply wrapping `make::ast_from_text`.

6033: Make name resolution resolve proc macros instead of relying purely on the build system r=matklad a=jonas-schievink
This makes name resolution look at proc-macro declaration attributes like `#[proc_macro_derive]` and defines the right proc macro in the macro namespace, fixing unresolved custom derives like `thiserror::Error` (which can cause false positives, now that we emit diagnostics for unresolved imports).
This works even when proc-macro support is turned off, in which case we fall back to a dummy expander that always returns an error. IMO this is the right way to handle at least the name resolution part of proc. macros, while the *expansion* itself should rely on the build system to build and provide the macro DLL. It does mean that they may go out of sync, but we can provide diagnostics if that happens (something like "could not find macro X in crate Y – ensure that all files of crate Y are saved").
I think it is valuable to be able to reason about proc macros even when we can't expand them, since proc macro expansion can break between Rust releases or users might not want to turn it on for performance reasons. It allows us to provide better diagnostics on any proc macro invocation we're not expanding (like a weak warning that informs the user that proc macro support is turned off, or that it has been disabled because the server crashed).

6073: Dont unnecessarily unnest imports r=matklad a=Veykril
Fixes#6071
This has the side effect that paths that refer to items inside of the current module get prefixed with `self`. Changing this behavior is unfortunately not straightforward should it be unwanted, though I don't see a problem with this as prefixing imports like this with `self` is what I do personally anyways 😅. You can see what I mean with this in one of the tests which had to be changed in `crates/ssr/src/tests.rs`.
There is one test that i still have to look at though, ~~which I by accident pushed with `#[ignore]` on it~~, which is `different_crate_renamed`, for some reason this now doesn't use the crate alias. This also makes me believe that aliases in general will break with this. So maybe this is not as straight forwards as I'd hoped for, but I don't really know how aliases work here.
Edit: The failing test should work now
