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.
In a later commit, paths in templates will be resolved. This allows us
to render the path with appropriate qualifiers for its context. Here we
prepare for that change by updating existing tests where I'd previously
not bothered to define the items that the template referred to.
The methods `edits_for_file` and `find_matches_in_file` are replaced with just `edits` and `matches`. This simplifies the API a bit, but more importantly it makes it possible in a subsequent commit for SSR to decide to not search all files.
Also renamed find_matches to slow_scan_node to reflect that it's a slow
way to do things. Actually the name came from a later commit and
probably makes more sense once there's an alternative.
This is in preparation for a subsequent commit where we add special
handling for paths in the template, allowing them to be qualified
differently in different contexts.
Previously we had:
- Multiple rules
- Each rule had its pattern parsed as an expression, path etc
This meant that there were two levels at which there could be multiple
rules.
Now we just have multiple rules. If a pattern can parse as more than one
kind of thing, then they get stored as multiple separate rules.
We also now don't have separate fields for the different kinds of things
that a pattern can parse as. This makes adding new kinds of things
simpler.
Previously, add_search_pattern would construct a rule with a dummy
replacement. Now the replacement is an Option. This is slightly cleaner
and also opens the way for parsing the replacement template as the same
kind of thing as the search pattern.
5498: assists: change_return_type_to_result: clarify assist description r=matklad a=matthiaskrgr
I had a -> Option<PathBuf> fn, which I wanted to change to Result<PathBuf, _>, but despite advertising to do so, the assist did not change the result type to Result<PathBuf, _> but instead just wrapped it in a Result: <Result<Option<PathBuf>, _>.
I changed the assist description to "Wrap return type in Result" to clarify that the assist only wraps the preexisting type and does not do any actual Option-to-Result refactoring.

5497: Store macro invocation parameters as text instead of tt r=jonas-schievink a=lnicola
We don't want to expand macros on every source change because it can be arbitrarily slow, but the token trees can be rather large. So instead we can cache the invocation parameters (as text).

5467: Allow null or empty values for configuration r=matklad a=kjeremy
Allow the client to respond to `workspace/configuration` with `null` values. This is allowed per the spec if the client doesn't know about the configuration we've requested.
This also protects against `null` or `{}` during initialize. I'm not sure if we want to interpret `{}` as "don't change anything" but I think that's a reasonable approach to take.
This should help with LSP clients working out of the box.
Fixes#5464

It is currently unused, but, in the future, it will be used to:
* drive certain UX (symbols search by default will look only in the
members)
* improve performance (rust-analyzer will assume that non-members
change rarely)
If not specified, is_workspace member is inferred from the path

4676: proc_macro: fix current nightly/future stable ABI incompatibility r=matklad a=robojumper
With rust-lang/rust#72233, the proc_macro ABI has changed, leading to the `test_derive_serialize_proc_macro` test believing that `serde` wants to pass the struct name as a byte string literal instead of a string literal.
Fixes#4866.
