Hexify strings in EWW search queries

Previously, inputting "cats & dogs" would lose dogs because the
ampersand signifies a query parameter.  Instead, hexify each word while
preserving quotes with split-string.
* lisp/net/eww.el (eww--dwim-expand-url): Join hexified words together
with + separators, instead of replacing whitespace with +.
