Use [^z-a] for matching any character (anychar/anything) in rx

* lisp/emacs-lisp/rx.el (rx--translate-symbol):
* test/lisp/emacs-lisp/rx-tests.el (rx-any, rx-atoms):
Use [^z-a] instead of ".\\|\n" for anychar.

The new expression is faster (about 2×) and does not allocate regexp
stack space.  For example, (0+ anychar) now matches strings of any
size (bug#37659).
