[IR] Filter chars and codePoints from allowed to interpret function

These two functions apparently are represented in Kotlin as methods
of `kotlin.String`. Because of that we accidentally treated them as
builtins.

To also minimize such cases, added filtration by return type. We are
allowing to interpret only these functions that have primitive or
unsigned return type.
