Item12708: Fix dependency checking for configure

Move the parsing of module versions into Foswiki:Configure::Dependency
so there is only one version with unit tests.

Eliminate any loading of modules to recover version strings.  This can
cause all sorts of issues to configure.

This resolves issues with not detecting pseudo-installed modules.
