A tree traverser that prepares a compilation unit to be capture checked. It does the following:
- For every inferred type, drop any retains annotations, add capture sets to all its parts, add refinements to class types and function types. (c.f. mapInferred)
- For explicit capturing types, expand throws aliases to the underlying (pure) function, and add some implied capture sets to curried functions (c.f. expandThrowsAlias, expandAbbreviations).
- Add capture sets to self types of classes and objects, unless the self type was written explicitly.
- Box the types of mutable variables and type arguments to methods (type arguments of types are boxed on access).
- Link the external types of val and def symbols with the inferred types based on their parameter symbols.

Is this phase the standard typerphase? True for TyperPhase, but not for other first phases (such as FromTasty or Parser). The predicate is tested in some places that perform checks and corrections. It's different from ctx.isAfterTyper (and cheaper to test).
