Remove channel_is_canonical_is_reliable()

Browse Source 
This function once served to let circuits continue to be built over
version-1 link connections.  But such connections are long-obsolete,
and it's time to remove this check.

Closes #40081.

o Minor features (security):
- Channels using obsolete versions of the Tor link protocol are no
longer allowed to circumvent address-canonicity checks.
(This is only a minor issue, since such channels have no way to
set ed25519 keys, and therefore should always be rejected.)
Closes ticket 40081.
