Move quoted lambda funarg check and expand coverage

* lisp/emacs-lisp/macroexp.el (macroexp--expand-all):
Move check for incorrectly quoted lambda arguments from here...
* lisp/emacs-lisp/bytecomp.el (byte-compile-form):
... to here, which should provide more detection opportunities.
Expand the set of functions for which this check is performed, now
also for some keyword arguments.
