AronDemian f6cbbbfd95 [modern] Add Header element and styles
- Removed `#mw-head-base`.
- `#mw-page-base` -> `.mw-header-placeholder`.
- `#mw-head` moved down to `@height-header` to make space for new header.
- Content moved down to `@height-header + @height-tabs`.

Added Less variables:
- @height-header: 69px;
- @height-logo-icon: 50px;
- @height-header--inner: 54px;
- @height-tabs: 2.5em;

Style splits:
- Added Header.less
- @height-header: 2.5em;
