This enum is a bit weird, we're 1:1 mapping things almost hmmm

These two types are essentially similar, the only difference is whether they represent the decl site or the use site.
I haven't quite found a better way to reduce duplication.

Problem
Currently,
SwiftTypedefinesoptional,array,dictionary, andsetas distinct cases.However, these types are sometimes represented nominally (e.g.,
Optional<Int>).This fragmentation forces us to implement logic for both
.nominaland the specific cases (like.optional), leading to redundant code.More importantly, it creates a risk of logic desynchronization; in fact, I've encountered issues where logic was updated for one case but overlooked for the other.
Solution
This PR unifies these special types into the
.nominalcase.To preserve the original syntactic representation (such as
Int?or[Int]), I have introducedSwiftNominalType.SugarName.This allows us to handle these types as nominal while still maintaining their original "sugared" form in the grammar.
