K2: add test for KT-56520, case (2), constructors, Space subcase

In this test, both frontends resolve to fun Semaphore.
Both work this way because interface/class Semaphore classifiers are
clashed (ambiguity) and ignored.
K2 reports ambiguity for some similar cases,
but constructor resolve still ignores ambiguous classifiers when found.
(see FirScope.processConstructorsByName in ConstructorProcessing.kt)
