RFR: 8347996: JavaCompilation.gmk should not include ZipArchive.gmk

[Magnus Ihse Bursie]

JavaCompilation.gmk includes ZipArchive.gmk, which includes ToolsJdk.gmk, which in turns includes JavaCompilation.gmk. This causes a circular dependency, which is not ideal. Make handles this anyway, but when I was developing new functionality to the build system, I discovered that this became a blocker.

Fortunately, the solution is simple. We include ZipArchive.gmk to support the convenience argument SRCZIP. It is used only in a single place, when compiling demos, and we can just as well (and arguably even better) call SetupZipArchive directly there.
