[4.0] Defer loading of menu items until required

[wilsonge]

Pull Request for Issue #28614 .

Summary of Changes

Defers loading of the menu items until we actually need the information on the menu items. In certain cases this will mean that

Testing Instructions

1. Ensure menus load in the frontend on a normal single language site
2. Ensure menus load in the frontend on a multilanguage site
3. Ensure menus load in the backend
4. Update Joomla from 3.10 (multilanguage site) using the PR custom update site to this branch. It should now work after this patch.

Documentation Changes Required

Yes. Document menu items are being loaded later. This will only be relevant however for custom menus extending Joomla\CMS\Menu\AbstractMenu so should be an edge case.

@wilsonge Please wait a bit with merging, am just starting with tests ... even if it has already 2 good tests. But we should be very careful here.

[richard67]

That's one of the PR's (update tests) where I am really happy about the update packages built by drone for this PR. In pasz I had to build them myself "manually".

drone and appveyor both failing.
hard to figure what's going on...

[richard67]

Appveyor is a known issue ... Hannes is on it.
Drone seems to be the regular randomly happening timeout. We will see.

Please test #28647 for timeout issue.
