[roll] Roll fuchsia [netstack3] Avoid TCP Option Length calculation

When determining the payload size of a TCP segment only recalculate the
option length if we're sending variable size options. In the case where
there are no variable size options, we already know the option length
and can use our cached value.

This saves a round_trip into packet-formats, as well as some potentially
expensive type conversions along the way.
