RFR: 8371333: Optimize static initialization of SSLContextImpl classes and improve logging [v2]

[Sean Coffey]

> Introduce lazy static initialization logic to SSLContextImpl via use of the new LazyConstant API and improve logging output
> 
> As per JBS comments:
> 
> * Each subclass of AbstractTLSContext (TLSv10. TLSv11 etc) is being initialization at framework initialization time due to the getApplicableSupportedCipherSuites(..) calls made in static block. Such calls are unnecessary if the subclass isn't required. This is especially true for the default JDK configuration where TLSv10, TLSv11 protocols are disabled. I've moved logic to lazy initialization of these fields via LazyConstant
> 
> * The debug prints output never made clear what protocol version each cipher suite was being disabled for. Improved logging there
> * The debug prints never printed out the resulting set of enabled/allowed cipher suites
> 
> There's efficiency gain also in having one less call to the getApplicableEnabledCipherSuites method in the scenario where customized cipher suites are not in use.
