[jdk17u-dev] RFR: 8261433: Better pkcs11 performance for libpkcs11:C_EncryptInit/libpkcs11:C_DecryptInit

[Martin Doerr]

Backport of [JDK-8261433](https://bugs.openjdk.org/browse/JDK-8261433). p11_util.c needed some manual integration. The rest applies cleanly except Copyright year update. I had to disable `useNormativeMechFirst` because [JDK-8255409](https://bugs.openjdk.org/browse/JDK-8255409) is not in 17u (see 2nd commit). "test/jdk/sun/security/pkcs11" tests have passed. Please review!
