Currently, the --module-path option is being ignored during CDS dumping.

./bin/java -Xshare:dump --module-path mlib -Xlog:cds=info

[0.048s][info][cds] Info: the --module-path option is ignored when dumping the shared archive

This enhancement is for supporting the --module-path for CDS and AppCDS.

High-level requirements:
---------------------------------
At dump time:
- the --module-path info, such as the location field of each ModuleEntry will be captured in the shared archive header. It could be right after the boot class path and app class path info;
- initially, we will only support modular jar specified in the --module-path.

At run time:
- if a class is loaded from a modular jar from a module path, check need to ensure the path to the jar file is the same as during dump time. The timestamp and size of the jar should not change compared with dump time.
