RFR: 8375061: Multiple jpackage tool providers may share the same logging config [v3]

[Alexey Semenyuk]

> The patch addresses two issues:
>  - Each jpackage tool provider instance should have its own logging config instance.
>  - The test lib should be able to keep output from concurrently running tests isolated from each other.
> 
> These two fixes are bundled together because it is impossible to verify the jpackage implementation fix without fixing the test lib.
> 
> The test lib fix replaces all inheritable thread-local variables with scoped values. It fixes the interleaved output issue and simplifies the implementation.
> 
> Supplementary changes:
>  - jdk.jpackage.internal.cli.Main: when creating a `java.io.PrintWriter` from a `java.io.PrintStream`, copy the charset instead of using the default one.
