Description
As part of JEP remove code related to Ahead-of-Time Compiler from JDK:

- `jdk.aot` module — the `jaotc` tool
- `src/hotspot/share/aot` — loads AoT compiled code into VM for execution
- HotSpot code guarded by `#if INCLUDE_AOT`

Additionally, remove tests as well as code in makefiles related to AoT compilation.
