LibJS: Add variant of to_integer_or_infinity() for plain doubles

Browse source 
In many cases we already know a certain value is a number, or don't have
JS values at all and would need to wrap doubles in a value. To optimize
these cases and avoid having to pass a global object into functions that
won't ever allocate or throw, add a standalone implementation of this
function that takes and returns doubles directly.
