Currently you cannot have menus inside dropdowns. To support this
we should limit the selector to direct children nodes.
This will allow us to put the main menu into the main menu icon
dropdown.

Collapsed dropdowns are hidden via `opacity:0;` and
`visiblility:hidden;`. This doesn't prevent them from having a
height, which can be an issue when the language selector is
at the bottom of the page, producing a large gap near the footer.

This affects all dropdowns in Vector 2022, including the
user menu in the header and the language variants and
"more" menu in the article toolbar.
By relying on shared styles instead of separate implementations,
this change also reduces the size of the skins.vector.styles
module by 1.6kB (uncompressed).
Visual changes:
- The links in the user menu are now blue
- Dropdown links in the user menu and tabs are blue
- The dropdown labels in the tabs are black not dark gray.

Splits MenuDropdown styles into modern and legacy styles.
Leaves a common MenuDropdownCheckbox.less file (for lack
of a better name) for common styles related to the checkbox
behaviour and dropdown menu resets.
Adds a new file in common/mixins.less for a shared
dropdown mixin.
