[FE] Prohibit default arguments in expect declarations actualized via typealias

Cases when default argument inhertied from super class are allowed.

Some tests for default arguments already exist and can be found in
`testData/diagnostics/tests/multiplatform/defaultArguments`, for example
`annotationsViaActualTypeAlias.kt`.

compiler/testData/multiplatform/defaultArguments/methodDefaultArgsViaTypealias/jvm.kt:8:1: error: default argument values inside expect declaration 'A' are not allowed if it is actualized via typealias. Possible fix is to remove default argument values in members:
public constructor A(p: String = ...)
public final expect fun foo(p: String = ...): Unit
actual typealias A = AImpl
