bug#56739: 29.0.50; `cl-psetq' and `cl-psetf' fail to recognize symbol macros

[Wing Hei Chan]

The following form produces (2 2) due to the failure of detecting
dependencies involving symbol macros.

(cl-symbol-macrolet ((c a))
  (let ((a 1) (b 2))
    (cl-psetq a b
              b c)
    (list a b)))

It should have behaved the same as the following form without symbol
macros, that is, producing (2 1).

(let ((a 1) (b 2))
  (cl-psetq a b
            b a)
  (list a b))
