jdlrobson 018f30c615 [Refactor] Simplify searchbox layout rules
Follow up to I340b9e7e91960713c0ebb4d3d26e2ae2d5628f37

The layout styles reference internal CSS classes within
Vector components that may change at any time.

For legacy layout, I leave the styles the same (they have a FIXME)
As Aron noted on code review the impact such a change
could have on user styles. For modern however I simplify the styles
as follows:
* The top margin on the form is promoted to the main element - this has
the same end result.
* Likewise the width dimensions are moved from child elements to
the parent
