Subject: os/input.c: parse keycodes in non-string context #7411

cb02137dfac7 had two mistakes, of the same nature: trans_special() must
be invoked with in_string=false unless the parsing context is a VimL
string. replace_termcodes() and input_enqueue() are low-level
mechanisms where VimL strings do not exist.

keymap.c: adjust double-quote case to satisfy keymap_spec.lua

closes #7410
