[Forwardport] Removed mageMenu widget dependency from breadcrumbs component #15178

[vovayatsyuk]

This is a cherry-pick of #15178

Description

For now, breadcrumbs on the product page hardly rely on mageMenu widget. This commit completely removes this dependency to allow to use third-party menus.

Fixed Issues

1. Invisible breadcrumbs at product page when mageMenu widget is not used #14987: Invisible breadcrumbs at product page when mageMenu widget is not used

Manual testing scenarios

1. Open app/code/Magento/Theme/view/frontend/templates/html/topmenu.phtml
2. Remove the following code from the template:

data-mage-init='{"menu":{"responsive":true, "expanded":true, "position":{"my":"left top","at":"left bottom"}}}'

3. Navigate to the product page.
4. Breadcrumbs are not rendered.

Comments

• I removed categoryId from the crumb name, since links id is a random number generated by jQueryUI menu. It has nothing to actual category id.
• Two tests where removed, because I removed _init method completely
