Move implementation specific comment 
This comment is about how the functions are implemented, not about their
public interface, so it doesn't belong in the header file.
It applies to everything in constant_time.c so moved there.

Unify equality checker functions return value 
The equality checker functions always return 0 or 1 value,
thus the type of return value can be the same dispite of the

b9930e7d70 Add dummy tls1.3 handshake dispatch functions 
Base on version config, `handshack_{clinet,server}_step`
will call different step function. TLS1.3 features will
be gradully added base on it.

And a new test cases is added to make sure it reports
`feature is not available`.

tls1.3 and tls1.2 can not be enabled at same
time before #4832 resolved.

And the test won't run into `handshake` stage, add
`skip_handshak_check` function to skip it.
