LibCrypto+LibJS: Remove the create_from methods from BigInteger

Browse source 
Instead we just use a specific constructor. With this set of
constructors using curly braces for constructing is highly recommended.
As then it will not do too many implicit conversions which could lead to
unexpected loss of data or calling the much slower double constructor.

Also to ensure we don't feed (Un)SignedBigInteger infinities we throw
RangeError earlier for Durations.
