Prohibit non-const expressions through varargs in annotations

Fixes #KT-23153 for Kotlin 1.3 The problem was in the type check of expression type against expected type. When feature `AssigningArraysToVarargsInNamedFormInAnnotations` (KT-20171) appeared, expected type could be wrong, which led to failed type check
