[4.0] Migrate com_menus to services

[laoneo]

Pull Request for Issue #20487.

Moves com_menus to the service based extension setup. Additionally it makes extensions work which do route their views completely to the back end.

See #20217 for details.

Very hard to test this as git apply does not work with it.
After trying some stuff (renaming and moving some files, I do get
`0 Class 'Joomla\Component\Menus\Administrator\Helper\JTable' not found' when selecting menu items associations in com_associations

Not sure this is related to the PR as I may have been wrong in applying the patch

[infograf768]

Looks also like we still have a call to MenusHtml line 248 of /administrator/components/com_menus/tmpl/items/default.php
it should be
<?php echo JHtml::_('menus.association', $item->id); ?>

Can you please update the since tags to deploy Version?

@infograf768 fixed the issues.

@laoneo
git apply still does not work with this PR.
As it is quite a job to apply this patch with eclipse (it does not rename and move files around and does not create new folders), could you give a link to your branch for us to download, install and test? I could not find the Digital-Peak:j4/service/menus branch.

Here we go https://github.com/Digital-Peak/joomla-cms/tree/j4/service/menus

I do not have the errors I remarked before. Menu items associations look like working fine too.

[laoneo]

So can we mark it as successful?

[infograf768]

I have tested this item ✅ successfully on e5eb507
