qmake: Split up logic for enumerating plugins from how they are processed

Sanitizing the contents of the QTPLUGIN variable, and adding default
plugins from the available modules, should be a separate step before
the resulting QTPLUGIN is iterated and processed by for example linking
to each plugin, generating an import file, and adding module dependencies.

This makes it easier to add logic to the processing step later on.
