LibJS: Publicly expose double_to_string and rename it number_to_string

Browse source 
Rename it to match the name used by the spec.

Add an override mode to skip formatting numbers with an exponential sign
(e.g. 1e23). This mode is needed by Number and Intl.NumberFormat, who
don't call out a specific number-to-string method to use (they just say
to make "the String consisting of the digits of n").
