On my QEMU with `Zvkned` extension enabled the `test/hotspot/jtreg/compiler/codegen/aes/TestAESMain.java` test is OK. I know that currently hardware implementing this extension is not available on the market but I suppose this PR can be a good starting point on supporting AES intrinsics for RISC-V in OpenJDK.

Thank you, looks good!
