RFR: 8371450: AES performance improvements for key schedule generation

[Shawn M Emery]

This fix improves performance in the AES key schedule generation by eliminating an unnecessary object and unnecessary mask in the inverse key schedule.

The micro:org.openjdk.bench.javax.crypto.AESReinit benchmark results are improved by 6.96% for arm64 and 7.79% for x86_64.

Thank you @jnimeh for catching the unnecessary byte mask!
