REGTESTS: ssl: split tls*_reuse in stateless and stateful resume tests

Simplify ssl_reuse.vtci so it can be started with variables:

- SSL_CACHESIZE allow to specify the size of the session cache size for
  the frontend
- NO_TLS_TICKETS allow to specify the "no-tls-tickets" option on bind

It introduces these files:

- ssl/tls12_resume_stateful.vtc
- ssl/tls12_resume_stateless.vtc
- ssl/tls13_resume_stateless.vtc
- ssl/tls13_resume_stateful.vtc
- quic/tls13_resume_stateless.vtc
- quic/tls13_resume_stateful.vtc
- quic/tls13_0rtt_stateful.vtc
- quic/tls13_0rtt_stateless.vtc

stateful files have "no-tls-tickets" + tune.tls.cachesize 20000
stateless files have "tls-tickets" + tune.tls.cachesize 0

This allows to enable AWS-LC on TCP TLS1.2 and TCP TL1.3+tickets.

TLS1.2+stateless does not seem to work on WolfSSL.
