Allow sender channel with generic cipherspec with receiver channel with specific cipherspec

This is particularly useful to those that want to convert to a generic cipherspec without having to worry whether their partner is using a generic cipherspec.

Behavior verified in MQ 9.4.0.11 on Windows

If the sender channel is using  ANY_TLS12_OR_HIGHER and the corresponding receiver channel is using ECDHE_RSA_AES_256_GCM_SHA_384, the channel won't start

If the receiver channel is using a generic cipherspec and the sender channel is using the specific one, the channel will start.
The same way if both channels are using a generic cipherspec the channel will start.

Expected behavior: if the receiver channel is using a specific cipherspec that is in the list for the generic cipherspec of the sender channel, the channel should start/run.
