RFR: JDK-8308398 Move SunEC crypto provider into java.base [v2]

[Anthony Scarpino]

> Hi,
> 
> I need a code review for moving the contents of the jdk.crypto.ec module into java.base.  This moves the SunEC JCE Provider (Elliptic Curve) into java.base.  EC has always been separate from the base module/pkg because of its dependence on a native library.  That library was removed in JDK 16.  An empty jdk.crypto.ec module will remain for compatibility, but marked as deprecated with the intent to be removed in a future release.
> 
> There should be no compatibility risk for application using EC through JCE. There are no public API changes to EC, XEC, and EdDSA classes .  Applications that unwisely accessing internal EC classes will need to use the java.base module.
> 
> Thanks
> 
> Tony
