Damien Neil a7551fe245 net: use synthetic network in TestDialParallel
TestDialParallel is testing the Happy Eyeballs algorithm implementation,
which dials IPv4 and IPv6 addresses in parallel with the preferred
address family getting a head start. This test doesn't care about
the actual network operations, just the handling of the parallel
connections.

Use testHookDialTCP to replace socket creation with a function that
returns successfully, with an error, or after context cancellation
as required.

Limit tests of elapsed times to a check that the fallback deadline
has been exceeded in cases where this is expected.

This should fix persistent test flakiness.

Fixes #52173.
