emacs-29 39fea115515 2/3: Do not store :lisp-dir in package descriptors

[Philip Kaludercic]

branch: emacs-29
commit 39fea1155150b48344cd9971c6248bc7b7a369f9
Author: Philip Kaludercic <philipk@posteo.net>
Commit: Philip Kaludercic <philipk@posteo.net>

    Do not store :lisp-dir in package descriptors
    
    * lisp/emacs-lisp/package-vc.el (package-vc--main-file)
    (package-vc--unpack-1): Query 'pkg-spec' instead of
    'package-desc-extras'.
    (package-vc--unpack): Do not update 'package-desc-extras'.
    
    This simplification is possible due to the change in 2718bbb3bc, since
    we now ensure that package specifications are not lost.  They are
    either provided by a package archive or stored in
    'package-vc-selected-packages'.
