Convert several test modules and remove .module files [2]

I forgot to link the parent issue some of those cannot be converted and that is too many

I found .module files in these modules too. should these be changed too

• views_test_data
• views_test_rss
• toolbar_test
• common_test
• deprecation_test
• entity_test
• hook_collector_on_behalf_procedural
• hook_collector_skip_procedural
• hook_collector_skip_procedural_attribute
• module_implements_alter_test
• module_test
• olivero_test
• pager_test
• system_test
• theme_region_test
• theme_test
• twig_theme_test

I have added the parent issue, the ones in the evaluate list that do not have an issue are able to be worked on.

A couple of notes, try to keep changes to around 200 lines so if a module is small you can do another, but if there is a lot to convert then do not.

Don't convert template_preprocess_HOOKs in this issue either.

Thanks!
