[IE9] Layout flex-box adjustments

Minor visual fix for IE9 for modern mode with search not in header.
i.e. with these settings:

    $wgVectorIsSearchInHeader = false;
    $wgVectorDefaultSkinVersion = 2;

Slight refactor of CSS. Removes block of styles that "reset" floats.
These were uneccessary because as flex-children, the floats were
ignored on those elements anyway.

Moves flex-wrap on .mw-header from layout-search-header.less
to layout-default.less since that's where display:flex is defined
and the rule is general enough that it should apply for different layouts.

Remove the @supports block with the `float:none;`. That is unnecessary
because flex-children are not affected by floats.
