K2: library-tests/java-lang-number-conversions: Accept changes

With
    fun f(b: kotlin.Byte) {
        val x = b.describeConstable()
    }
and -language-version 1.9 we get
    test.kt:2:15: warning: 'describeConstable(): Optional<DynamicConstantDesc<Byte!>!>!' is deprecated. This member is not fully supported by Kotlin compiler, so it may be absent or have different signature in next major version
and with 2.0
    test.kt:2:15: error: unresolved reference 'describeConstable'.
