modules/lazyload: replace ignoredPackages with isVisible

Instead of explicitly listing all renames and removals, we can check if
the plugin's lazyload option is visible and in the top-level option set.

This rules out cases where `plugins.foo` is itself a rename/removal
option, and cases where `plugins.foo.lazyload` is not visible.
