RFR: 8356192: Enable AOT code caching only on supported platforms

[Vladimir Kozlov]

@TheRealMDoerr reported failures in `runtime/cds/appcds` testing on PPC64 after [JDK-8350209](https://bugs.openjdk.org/browse/JDK-8350209) integration.

AOT code caching should be limited to supported platforms: x64 and aarch64.

Testing: GHA
