Jan Drewniak 4ab2b1bff1 Refactor Vector tabs layout for reduced size & complexity
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.
