RFR: 8258852: Arrays.asList() for single item could be replaced with Collections.singletonList()
If there is only one item, the call to Arrays.asList() could be replaced with Collections.singletonList() for less memory occupation. This update also includes some other code cleanup, like redundant variables in the related files. Code cleanup only, no new regression test.

The local variable "knownSignatureSchemes" in the CRSignatureSchemesConsumer.consume() method is assigned, but it is not really queried. It is safe to remove the local variable and the related code.

Since JDK 11, this code path would have thrown an SSLException. I've chosen to keep that instead of introduce another Exception(UnsupportedOperationException) -- which would be new for some application stacks. I've looked at the apache core-http stack and know that it catches and ignores SSLException in these cases. The important change here is that the exception is not fatal and the session remains valid.
