6477: Add infer_function_return_type assist r=matklad a=Veykril
This adds an assist to insert a functions return type if it hasn't been specified yet by inferring it from the functions tail expression. This assist only becomes active if the cursor is on the tail expression. See https://github.com/rust-analyzer/rust-analyzer/issues/6303#issuecomment-714657326

Folks report a ton of hard-to-diagnose issues, the solution for which
is "unset RUST_SRC_PATH". Let's just ignore RUST_SRC_PATH when it
won't work anyway!
6456: Support record variants in extract_struct_from_enum_variant r=matklad a=Veykril
As requested :)
This also prevents the assist from being disabled if a definition in the value namespace exists with the same name as our new struct since that won't cause a collision

6458: Qualify trait impl created by add_custom_impl assist r=matklad a=Veykril
When we find at least one trait with the same name as the derive accessible from the current module we now generate a qualified path to that trait in the generated impl.
If we don't find any we just do what was done before and emit the trait name in the generated impl.

This also seizes the opportunity to move integer literal parsing to
the syntax crate, were it logically belongs.
Note though that this is still done in an ad hoc manner -- we probably
should split kitchen sink ast::Literal into a separate APIs for
strings, ints, etc
6287: Don't replace entire module and file nodes when inserting imports r=matklad a=Veykril
This change minifies the resulting diff of import insertions by inserting or replacing the produced use tree directly through an `action` return value instead replacing the entire container node. This action has to be applied by the caller now. This unfortunately pulls the `AssistBuilder` into scope of `insert_use` back again but I tried to at least keep it away from the `insert_use` fn itself.
I'm open to more/better ideas regarding this :)
Fixes#6196

6401: Only show `self` ident when showing parameter self hints r=matklad a=Veykril
This just hints all self parameters with the `self` token, this is therefor equal to how all other parameters are displayed, but given the self param special in how its defined in a function signature it might make sense to keep the `&`/`&mut` parts as well as emitting those tokens for explict `Self` types that are taken by ref like `self: &Rc<Self>`?
Fixes#6400

6435: Test Fixture ExplicitRoot + ModuleResolutionRelativePathOutsideRoot. r=matklad a=rickvanprim
Updates `module_resolution_relative_path_outside_root` test to check valid paths outside of the root, by moving the root to a subpath so that paths outside of it are possible. If this would be more appropriate as a new test, or if the original check for an invalid path should be left, I'm happy to update.

6430: Move completions rendering into a separate module r=popzxc a=popzxc
This PR extracts rendering-related things from `Completions` structure to the new `render` module.
`render` module declares a `Render` structure (which is a generic renderer interface), `RenderContext` (interface for data/methods not required for completions generating, but required for rendering), and a bunch of smaller `*Render` structures which encapsulate logic behind rendering a certain item.
This is just a step in full separation direction, since the following this are still to be done:
- Move some data from `CompletionContext` to the `RenderContext`;
- Forbid any kind of rendering outside of `render` module;
- Extract score computing into a separate module.
This PR is already pretty big, so not to make it even harder to review I decided to split this process into several subsequent PRs.
