Fix pcase 'rx' patterns with a single named submatch (bug#48477)
pcase 'rx' patterns with a single named submatch, like
(rx (let x "a"))
would always succeed because of an over-optimistic transformation.
Patterns with 0 or more than 1 named submatches were not affected.
Reported by Philipp Stephani.
* lisp/emacs-lisp/rx.el (rx--pcase-macroexpander):
Special case for a single named submatch.
* test/lisp/emacs-lisp/rx-tests.el (rx-pcase): Add tests.
