K2: Refine mapping of primitive arrays to JVM descriptor

Earlier, it wasn't really important but after the previous commit
when JvmMappedScope semantics has been changed, we erroneously
started loading `toCharArray` as a member to String because
its jvmDescriptor was computed to "toCharArray()Lkotlin/CharArray",
while hardcoded information that prevents it from loading expect
"toCharArray()[C" there.
