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.

Consolidates the CSS responsible for styling chevrons into one
implementation. This removes the need for custom padding and
background positioning for the following components:
- "more" menu
- user menu
- watchstar
- language button
- languge button in sticky header
Instead of absolutely positioning the chevron on these components,
the parent label element is set to `display: inline-flex` so that
the chevron is vertically aligned and given enough space by default.
The watchstar, although not a chevron, is also given the
`display: inline-flex` treatment so that it can be aligned with
other elements in the toolbar.
This new implementation requires splitting the watchstar
component into legacy and modern due to a quirk in Firefox that
causes a bug with the watchstar in legacy Vector.
NOTE: This change causes visual changes due to the difference in
centering the chevrons via flexbox vs percentage positions.

Fix for iOS Safari 13 & 14 (T309223):
- Replaces flex-box layout from the top-level #right-navigation
and #left-navigation tab elements with floats.
Then for vertical alignment, sets the child <li> elements and
<a> elements to inline block.
Opportunistic refactor (T308344):
- Moves the font-size rules to top-level #left/right-navigation,
but leaving them as-is for legacy Vector.
- Removes a (seemingly) unnecessary `display:none` rule from
Vector 2022, which previously applied to H3 labels in the
sidebar, which are no longer targeted by the styles in
MenuTabs.less.
- Removes an unnecessary selector and duplicated rules from
ArticleToolbar.less
This change fixes a flexbox issue on iOS Safari 13 & 14, but also
reduces the CSS bytesize of the skins.vector.styles module by
0.9kB (uncompressed), from 54.2kB in the previous commit to
53.3kB with this commit.
Expected visual changes:
* The tab underline now overlaps with the toolbar underline, and text
pushed down on certain tabs
* The variant tab is now equally spaced
* Right navigation tabs slightly shifted to the right
Unexpected visual changes:
* More menu shifts to the left [see note at top of commit, will be
fixed in a follow up]
NOTE: this introduces a visual regression in the mobile viewport in that
the more menu.
Given this viewport is still experimental, after talking to Jan
we agreed to address this in a follow-up.
NOTE: Update addresses the reason for revert 5599cf2 and compatibility
with CSS Grid layout by adding a clearfix (display:flow-root)
for #right-navigation and #left-navigation elements inside toolbar.

Removes gradients from tabs (i.e. article toolbar) in new Vector, moving
the existing MenuTabs.less component into the skins.vector.styles.legacy module
and creating a new MenuTabs.less component for modern Vector.
