TotalDurationNanoseconds previously return a double to represent the
total duration nanoseconds, but the value could be easily bigger than
the precise value a double can represent. A double can precisely
represent integer to 2^53, which is only about 104 days if that value
is nanoseconds. So we need to change the return type to BigInt.

Refactor BalanceDuration to merge common code.

Change JSTemporalDuration::Compare to use the BigInt version of
TotalDurationNanoseconds
Change the call site of TotalDurationNanoseconds in  RoundDuration

Add newly defined BalancePossiblyInfiniteDuration and change
BalanceDuration to call it.
