[FIX] website: add tests for #64446

As `standalone` tests were introduced in 14.0 (see 0453566a), this commit
adds tests to ensure the `inherit_id` of COW views are correctly updated on
module updates.
This test could not be rewritten in a regular test and merged in 12.0 as module
operation in tests try to be avoided (see 5e7e7b00b7d).

See #64446 for more information about the original fix.

+This test ensure `inherit_id` update is correctly replicated on cow views.
+The view receiving the `inherit_id` update is either:
+1. in a module loaded before `website`. In that case, `website` code is not
+   loaded yet, so we store the updates to replay the changes on the cow views
+   once `website` module is loaded (see `_check()`). This test is testing that
+   part.
+2. in a module loaded after `website`. In that case, the `inherit_id` update is
+   directly replicated on the cow views. That behavior is tested with
+   `test_module_new_inherit_view_on_parent_already_forked` and
+   `test_specific_view_module_update_inherit_change` in `website` module.
