[crac] RFR: 8372933: [CRaC] Restore failed due to incompatible or missing CPU features, try using -XX:CPUFeatures=0xfoo,0xbar on checkpoint

[Jan Kratochvil]

Since [JDK-8368929](https://bugs.openjdk.org/browse/JDK-8368929) the message:

Restore failed due to incompatible or missing CPU features, try using -XX:CPUFeatures=0xe14e1805fdfbf7,0xfcc on checkpoint.

is wrong as it does not do logical and of both CPUFeatures masks.

Yes, I should have caught it during [JDK-8368929](https://bugs.openjdk.org/browse/JDK-8368929) review.

@rvansa will probably want to change the API but this is a PoC how it should work.

It is in fact untested as I haven't run it with CRIU yet.
