fix(codebuild): setting Cache.none() renders nothing in the template #18194

When implementing caching in CodeBuild,
we made the default cache Cache.none(),
and, for that reason, do not render anything in the template for that type of cache.
However, that does not work well with the CodeBuild API,
which interprets the lack of a property as the signal to leave it unchanged.
Which means it's not possible currently to disable caching on a Project once it has been enabled once.

Fix this by differentiating between the case of "no Cache has been provided",
and "the none() Cache has been provided".

Closes #18165

@rix0rrr I've changed the default like you asked. As you can see, this resulted in a lot of changes. Let me know if you still want to proceed with this direction - if so, I'll update the PR title and description. Thanks!
