New seq-contains-p predicate (Bug#34852)
* lisp/emacs-lisp/seq.el (seq-contains-p): New predicate function. It is a replacement for seq-contains which cannot be used as a predicate when a sequence contains nil values as it returns the element found. (seq-contains): Make obsolete. * test/lisp/emacs-lisp/seq-tests.el (test-seq-contains-p): (test-seq-intersection-with-nil, test-seq-set-equal-p-with-nil, test-difference-with-nil): Add regression tests. * doc/lispref/sequences.texi (Sequence Functions): Document seq-contains-p.
