feat(search): support remove icon

Support remove icon for search module similar to dropdown module
Either via separate remove icon or by using a native input[type="search"] element

Sidenote
I party reused code which was already implemented in 2015 but removed again (by accident or intentionally , only the original authors knows...)
That's why i also removed the left dead css code for selection search which never made it into any release and wasn't ever documented.
