Support styled function components

[finkef]

When trying to use styled without the string alias like styled("View", ...), but with an actual component like styled(View, ...), I'm getting this error:

Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports

This is due to a missing check for typeof component === "function". Also, cloneElement is used rather than createElement after the typeof component === "object" check which I assume was to allow using styled for React.memo'ed components already created by styled("View", ...). Note that createElement works with memoized components as well as with any other function or class component.
