Add the macro type-print test to run-macros-scala2-library-tasty.blac…

…klist (#21787)

Just noticed the ci issues. The actual changes in the .check files
concern `TypeRef(ThisType(TypeRef(NoPrefix(), "immutable")), "List")`
(read from byte code) being shown as
`TypeRef(TermRef(TermRef(TermRef(ThisType(TypeRef(NoPrefix(),
"<root>")), "scala"), "collection"), "immutable"), "List")` (read from
tasty), which is expected and also happens in the other excluded tests
