RFR: 8368030: Make package bundlers stateless [v2]

[Alexey Semenyuk]

> Introduce `jdk.jpackage.internal.SystemEnvironment` interface to describe system tools needed for building specific package bundles with three immediate subinterfaces: `WinSystemEnvironment`, `LinuxSystemEnvironment`, and `MacDmgSystemEnvironment`.
> 
> `LinuxSystemEnvironment` has two subinterfaces: `LinuxDebSystemEnvironment` and `LinuxRpmSystemEnvironment`.
> 
> There is no `MacSystemEnvironment` interface as pkg and dmg bundlers are unrelated, unlike rpm and deb bundlers, which share a fair amount of code.
> 
> There is no `MacPkgSystemEnvironment` interface because the pkg bundler doesn't validate tools.
> 
> Instances of these interfaces are created as member fields of the corresponding bundler classes, i.e., bundling system tools are validated only once when a specific bundler is instantiated.
> 
> Move the bundling code away from *Bundler classes into *Packager classes and completely isolate it from the "params". This is a follow-up for the effort to isolate the "params" in [JDK-8333664](https://bugs.openjdk.org/browse/JDK-8333664).
