3692: Introduce `MacroDefKind::CustomDerive` r=matklad a=edwin0cheng
This PR introduce a new `MacroDefKind` `CustomDerive`. And use a new `ProcMacroExpander` for its expanding. And the expander is a dummy for now.

3707: Add ItemScope::visibility_of r=matklad a=edwin0cheng
~This PR implements `HasVisibility` for various constructs and change `Definition::search_scope` to use `Visibility` directly instead of depends on ad-hoc string parsing.~
This PR added `visibility_of` in `ItemScope` and `Module` and use it directly directly instead of depends on ad-hoc string parsing.
And also add a FIXME to indicate that there is a bug which do not search child-submodules in other files recursively in `Definition::search_scope`.
I will submit another PR to fix that bug after this is merged.

3710: Inlay hints for method chaining pattern r=matklad a=M-J-Hooper
This PR adds inlay hints on method call chains:
It is not only explicit `MethodCall`s where this can be helpful. The heuristic used here is that whenever any expression is followed by a new line and then a dot, it resembles a call chain and type information can be #useful.
Changes:
- A new `InlayKind` for chaining.
- New option for disabling this type of hints.
- Tree traversal rules for identifying the chaining hints.
- VSCode decorators in the extension layer (and associated types).
Notes:
- IntelliJ has additional rules and configuration on this topic. Eg. minimum length of chain to start displaying hints and only displaying distinct types in the chain.
- I am checking for chaining on every `ast::Expr` in the tree; Are there performance concerns there?
This is my first contribution (to RA and to Rust in general) so would appreciate any feedback.
The only issue I can find the references this feature is #2741.
