RFR: 8354887: Preserve runtime blobs in AOT code cache [v2]

[Ashutosh Mehra]

> [8350209](https://bugs.openjdk.org/browse/JDK-8350209) introduced the framework for storing code in aot code cache and used it for caching i2c/c2i adapters.
> This PR extends the `AOTCodeCache` infrastructure and stores various runtime blobs (shared blobs, C1 and C2 runtime blobs) in the AOT code cache. It adds a new diagnostic flag `AOTStubCaching` to enable/disable the caching of these blobs.
> `AOTCodeFlags.java` test is extended to cover `AOTStubCaching`.
