    Fix runtime.nearest.num condition & round towards zero instead of with negative bias

commit 2b3713df25e67dd1c2269b6e53bc4adef6b8ffbf
Author: Hexcede <8394472+Hexcede@users.noreply.github.com>

    Add runtime.min.num & runtime.max.num

    Wasm min/max returns NaN if either operator is NaN. However, Luau min/max follows different behaviour.
