tcp: improve timestamp rtt accuracy
- switch to using vlib_time as reference for timestamps - use us precision ticks for tcp but keep using ms precision for timestamps. As a result, srtt, rttvar and rto are now measured in us instead of ms. MRTT samples from timestamps are converted from ms to us (not accurate under ms) while high precision samples are used with us precision, i.e., they're no longer converted to ms precision samples.
