[FIR2IR] Convert data class properties of type dynamic for hashCode

Properties of type dynamic within a data class cause compilation to fail
when converting FIR to IR. This is because dynamic types do not have a
proper backing class for symbol lookup. However, dynamic types can just
be considered of type Any for hashCode calculations.
