RFR: 8338017: Add AOT command-line flag aliases

[Ioi Lam]

This is the first PR for [JEP 483: Ahead-of-Time Class Loading & Linking](https://bugs.openjdk.org/browse/JDK-8315737).

Add the following command-line options as specified in JEP 483:


- `-XX:AOTMode=off/record/create/auto/on`
- `-XX:AOTConfiguration=<file>.aotconfig`
- `-XX:AOTCache=<file>.aot`

These options are implemented as aliases to existing command-line flags such as `-Xshare:dump`, `-XX:SharedArchiveFile`, `-XX:DumpLoadedClassesList`, etc.

Please see the CSR (TODO) for detailed specification.
