Allow uninstalling modules and the modules which are dependent in the same action

I think the proposed solution / approach only describes the easy path: dependent modules can be uninstalled. But there are situations where a dependent module can't be uninstall because it is used by entities (whatever it is config entity or content entity).

As a first step, we should probably authorise uninstall of modules which all dependent modules are uninstallable as well.

Please find a patch to initiate that work. I have not updated the tests on purpose as I do expect discussion.

I used the form states api to check dependent modules when a module is checked for uninstall.

Fixed CCF for #2.

Test failures.

Also believe will need test coverage.

"This gets quite tedious"
Not sure "tediousness" can be an issue.

Multi-step uninstall is pretty common to me. I find this process useful instead to better understand how that Drupal instance is made of.

Following though..

Postponing this only because uninstall can be destructive. I think manually checking the dependency tree is important.

Imagine we add this them someone uninstalled system, suddenly their site is just gone.

I think I would need a very convincing argument that the convenience of single step uninstall is outweighs the risks of accidentally uninstall to many modules.

Closing this as a duplicate of the related issue.
