5989: Rewrite import merging r=jonas-schievink a=Veykril
Rewrites how import merging is being handled. It is now a recursive function to properly handle merging of intermediate levels in the import trees. With this ordering the imports is also now possible tho it doesn't quite order it the same way as `rustfmt` does yet, namely it orders lowercase identifiers after uppercase identifiers as that is the standard character order that rust uses. This also fixes a few weird behaviors that were visible in some of the `replace_qualified_name_with_use.rs` tests.
This really took longer than I was hoping for, fighting with import trees is quite the exhausting task 😅

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.

We might want to provide more efficient impls for check if usages
exist, limiting the search, filtering and cancellation, so let's
violate YAGNI a bit here.
5776: Fix eslint errors on .eslintrc.js and rollup.config.js r=matklad a=fuafa
Eslint complains if these two files does not include in the `tsconfig.json`.
```
Parsing error: "parserOptions.project" has been set for @typescript-eslint/parser.
The file does not match your project config: .eslintrc.js.
The file must be included in at least one of the projects provided.eslint
```
5780: Fixup whitespace when adding missing impl items r=matklad a=jDomantas
Generate properly formatted whitespace when adding impl items - with an empty line between items and removing extra whitespace that often appears at the end.
This is my first time working on rust analyzer so I'm not very familiar with its internal APIs. If there's a better way to do such syntax tree editing I'd be glad to hear it.

Conjecture: it's impossible to use hir::Path *correctly* from an IDE.
I am not entirely sure about this, and we might need to add it back at
some point, but I have to arguments that convince me that we probably
won't:
* `hir::Path` has to know about hygiene, which an IDE can't set up
properly.
* `hir::Path` lacks identity, but you actually have to know identity
to resolve it correctly
