Nicholas Ray 3028a4f9d8 Refactor search component expand behavior and add auto-expand-width prop to search component
In preparation for I30c670e3f195f77a27715c6b494a3088b7a55712, refactor
the search component expand behavior so that it can accomodate the new
changes in WVUI while maintaining backwards compatibility with the
status quo.

Additionally, pass/enable the `auto-expand-width` prop to the main
header's search. This will be inert until the new changes in WVUI have
landed.
