QUIC: lower bound path validation PTO.

According to RFC 9000, 8.2.4. Failed Path Validation,
the following value is recommended as a validation timeout:

  A value of three times the larger of the current PTO
  or the PTO for the new path (using kInitialRtt, as
  defined in [QUIC-RECOVERY]) is RECOMMENDED.

The change adds PTO of the new path to the equation as the lower bound.
