5541: add completion for rustc lints r=matklad a=Emilgardis
This is a very naive approach to provide completions for lints.
Preferably, this would pull from current `rustup which rustc` via `rustc -W help <crate>`, but currently `rustc` only provides human output for lints.

also, clippy would be really nice but I feel like for that ra should really pull from clippy

5520: Add DocumentData to represent in-memory document with LSP info r=matklad a=kjeremy
At the moment this only holds document version information but in the near-future it will hold other things like semantic token delta info.

5516: Better LSP conformance r=matklad a=vsrs
At the moment rust-analyzer does not fully conform to the LSP. This PR fixes two LSP related issues:
1) rust-analyzer sends predefined server capabilities and does not take supplied client capabilities in mind.
2) rust-analyzer uses dynamic `textDocument/didSave` registration even if the client does not support it.

5518: Use resolved paths in SSR rules r=matklad a=davidlattimore
The main user-visible changes are:
* SSR now matches paths based on whether they resolve to the same thing instead of whether they're written the same.
* So `foo()` won't match `foo()` if it's a different function `foo()`, but will match `bar::foo()` if it's the same `foo`.
* Paths in the replacement will now be rendered with appropriate qualification for their context.
* For example `foo::Bar` will render as just `Bar` inside the module `foo`, but might render as `baz::foo::Bar` from elsewhere.
* This means that all paths in the search pattern and replacement template must be able to be resolved.
* It now also matters where you invoke SSR from, since paths are resolved relative to wherever that is.
* Search now uses find-uses on paths to locate places to try matching. This means that when a path is present in the pattern, search will generally be pretty fast.
* Function calls can now match method calls again, but this time only if they resolve to the same function.

This differs from how this used to work before I removed it in that:
a) It's only one direction. Function calls in the pattern can match
method calls in the code, but not the other way around.
b) We now check that the function call in the pattern resolves to the
same function as the method call in the code.
The lack of (b) was the reason I felt the need to remove the feature
before.
Previously, submatches were handled simply by searching in placeholders
for more matches. That only works if we search all nodes in the tree
recursively. In a subsequent commit, I intend to make search not always
be recursive recursive. This commit prepares for that by finding all
matches, even if they overlap, then nesting them and removing
overlapping matches.
