RFR: 8348890: Fix docs for -XX:AOT* options in java man page

[Ioi Lam]

Some problems in the `-XX:AOT*` docs are found after [JDK-8348515](https://bugs.openjdk.org/browse/JDK-8348515) was integrated. See @rose00  comments in #23287

- The default of `AOTClassLinking` is incorrect
- "AOTCache" should be changed to "AOT cache" in the descriptive text
- There are some typos
