Fix Edebug spec for cl-macrolet (bug#29919)

Add an Edebug matching function for cl-macrolet which keeps track of
its bindings and treats them as macros without Edebug specs when found
in the body of the expression.
* lisp/emacs-lisp/edebug.el (edebug--cl-macrolet-defs): New variable.
(edebug-list-form-args): Use it.
(edebug--current-cl-macrolet-defs): New variable.
(edebug-match-cl-macrolet-expr, edebug-match-cl-macrolet-name)
(edebug-match-cl-macrolet-body): New functions.
* lisp/emacs-lisp/cl-macs.el (cl-macrolet): Use cl-macrolet-expr
for Edebug spec.
* test/lisp/emacs-lisp/edebug-tests.el (edebug-tests-cl-macrolet):
New test.
* test/lisp/emacs-lisp/edebug-resources/edebug-test-code.el
(edebug-test-code-use-cl-macrolet): New function.
