test: rework ephemeralkeyinfo to run in parallel
Remove:
- use of tls global so tests can run in parallel
- test counting in favour of common.mustCall()
- limit of only one cipher suite per ephemeral key type tested
The last change will allow adding TLS 1.3 cipher suites and testing 'ECDH' key info with them.
