8340327: A common framework to support public key algorithms with standard parameter sets

[GoeLin]

This is needed to backport the new Quantum-Resistant [1] algorithms.

Patching the original change to 21 first causes two issues:
It does not apply clean to SignatureUtil as
https://bugs.openjdk.org/browse/JDK-8302233: "HSS/LMS: keytool and jarsigner changes"
is not in 21.
I omit the patch to getDefaultSigAlgForKey() that modifies the
default entry of a switch.
The omitted patch just undoes the change of 8302233 for KEM.
Thus the patch is not necessary in 21 as long as 8302233 is not backported.

Further I had to adapt the @modules in test NamedEdDSA.java.
After 21 ec has been moved into java.base.

Then, the change needs a larger rework as https://bugs.openjdk.org/browse/JDK-8318096: "Introduce AsymmetricKey interface with a getParams method" is not in 21. This has a CSR and has not been backported by Oracle, so I don't want to backport it as prereq change. Also, adding an interface and new methods breaks the jck tests.

I replaced the instanceof AsymmetricKey statements with checks for PrivateKey or PublicKey.
I add a method getParams to KeyUtil.java that searches with reflection for the getParams() method of the Key and calls that. I need a privileged action to make the method accessible.
I added a test using a security manager. The tests needs no extra privileges once I add the privileged action.
