Merge #5643

5643: Add new consuming modifier, apply consuming and mutable to methods r=matklad a=Nashenas88

This adds a new `consuming` semantic modifier for syntax highlighters.

This also emits `mutable` and `consuming` in two cases:

- When a method takes `&mut self`, then it now has `function.mutable` emitted.
- When a method takes `self`, and the type of `Self` is not `Copy`, then `function.consuming` is emitted.
