[lworld] RFR: 8376088: [lworld] value class creation in CompileJavaModules.gmk leaves unnecessary files [v5]

[David Beaumont]

> This is a tidying up of the value class generation and management.
> It solves JDK-8376088, but also simplifies the two-step process for creating the `META-INF/preview` class files.
> 
> Short description of changes:
> 1. Remove JAR file creation (no longer needed, this is the proximal fix for JDK-8376088).
> 2. Stop adding the "intermediate" target for the compilation to the TARGETS list (rely on the subsequent copy).
> 3. Copy directories directly from the output directory to the preview directory (does not copy marker files).
> 4. Make the marker file appear alongside other markers for the module compilation.
> 5. Rename marker file to be consistent with other sibling marker files.
> 
> The marker files in `build/linux-x64/jdk/modules/java.base/` are now:
> 
> 
> _the.java.base_batch
> _the.java.base_batch.cmdline
> _the.java.base_batch.filelist
> _the.java.base_batch.log
> _the.java.base_batch.modfiles
> _the.java.base_batch.modfiles.fixed
> _the.java.base.config_vardeps
> _the.java.base_internalapi
> _the.java.base-javacserver.conf
> _the.java.base_pubapi
> _the.java.base.valueclasses   <-- moved/renamed mark file
> _the.java.base.vardeps
> 
> 
> I've added a couple of notes where there could be choices about the implementation.
