util: add inspect suffix to BigInt64Array elements

This commit updates `util.inspect` to add an `n` suffix to BigInts that
appear in BigInt64Arrays. BigInts are formatted with an `n` suffix in
most cases, but this did not occur in BigInt64Arrays due to an apparent
oversight where the implementation of `inspect` for typed arrays assumed
that all typed array elements are numbers.
