RFR: 8356597: AOT cache and CDS archive should not be created in read-only mode [v2]

[Ioi Lam]

> For some unknown historical reasons, AOT caches and CDS archives have been created in read-only mode. This makes them hard to delete, causing problems when running tests that creates a lot of these files.
> 
> Since all other JDK tools create binary files in read-write mode, AOT caches and CDS archives should do the same.
