Subject: [Swift] Add support for applying parameter and return types during
 demangling

This is disabled by default due to a current limitation where core is
not able to represent parameters that are small structs being passed
across multiple registers. `analysis.swift.extractTypesFromMangledNames`
can be enabled to test this.
