RFR: 8355003: Implement JEP 515: Ahead-of-Time Method Profiling [v15]

[Igor Veresov]

> Improve warm-up time by making profile data from a previous run of an application instantly available, when the HotSpot Java Virtual Machine starts. Specifically, enhance the [AOT cache](https://openjdk.org/jeps/483) to store method execution profiles from training runs, reducing profiling delays in subsequent production runs.
