RFR: 6447816: Provider filtering (getProviders) is not working with OR'd conditions [v4]

[Valerie Peng]

> Existing provider filtering code only handles two standard attribute "KeySize" and "ImplementedIn", the rest are compared by exact match. Over time, more standard attributes are added which contain multiple values separated by "|". We should enhance the provider filtering code to better compare these.
> 
> Documentation update for this is tracked separately under https://bugs.openjdk.org/browse/JDK-6447817.
> 
> Thanks in advance for review~
