Revert last commit

This reverts commit af4697faa1f5b643f63a9ea61aa205a4c1432e23.  It's
too late for this to be in the release.

Define if-let* and derivatives as aliases for if-let etc

This commit reverts declaring `if-let' and `when-let' obsolete in
favor of the new `if-let*' and `when-let*' versions because of the
compiler warning mess (Bug#30039).  Instead we make foo-let* aliases
for foo-let.  The old single-tuple variable spec case is still
supported for backward compatibility.
* lisp/emacs-lisp/subr-x.el (if-let, when-let): Don't declare
obsolete.  Tweak edebug specs.
(and-let): Renamed from `and-let*' for compatibility with the names
`if-let' and `when-let'.
(if-let*, when-let*, and-let*): Define as aliases for `if-let',
`when-let' and `and-let'.
* test/lisp/emacs-lisp/subr-x-tests.el (if-let-single-tuple-case-test)
(when-let-single-tuple-case-test): New tests for the single-binding
tuple case.
In the whole file, prefer the names without "*".

Minor fix in Emacs manual's Glossary

* doc/emacs/glossary.texi (Glossary): Fix outdated text about
primary selection.  Reported by Gijs Hillenius
<gijs@hillenius.net> in emacs-manual-bugs@gnu.org.
