Generate info/dir from .texi files rather than .info files

* Makefile.in (install-info): Handle missing info/dir.
(info_dir_deps): New variable.
(${srcdir}/info/dir): Depend on .texi files rather than .info files.
(check-info): Update topics.

* build-aux/make-info-dir: Use .texi files rather than .info files.
Update topics.

* doc/lispintro/emacs-lisp-intro.texi:
* doc/lispref/elisp.texi:
Tweak dircategory (all the others use "Emacs" + lower-case).
