[jdk21u-dev] RFR: 8335288: SunPKCS11 initialization will call C_GetMechanismInfo on unsupported mechanisms

[Goetz Lindenmaier]

I backport this for parity with 21.0.7-oracle.

I removed brokenMechanisms.contains() from the code. brokenMechanisms
was introduced by https://bugs.openjdk.org/browse/JDK-8324585 which is not 
in 21. But this is a change that might be backported at some point, so I 
think we should leave the code in there so that it's easier to recover it 
in this case.  I also wrote a note in 8324585 to do so.
