RFR: 8348515: Add docs for -XX:AOT* options in java man pages

[Ioi Lam]

I added docs for the following options added by [JEP 483](https://openjdk.org/jeps/483)

- -XX:AOTCache
- -XX:AOTClassLinking
- -XX:AOTConfiguration
- -XX:AOTMode

For a (semi) rendered version, see https://github.com/iklam/jdk/blob/8348515-docs-for-aot-options/src/java.base/share/man/java.md#ahead-of-time-cache

(Some of the rendering by GitHub looks odd, but the java.1 and java.html pages produced by the build should look fine)
