bug#66040: 30.0.50; The XF86AudioLowerVolume on keyboard cannot be detected correctly

[Wang, Zhenhua (MU-Student)]

The most recent version of Emacs doesn't recognize the XF86AudioLowerVolume key. I use "C-h k" to check this in "emacs -Q". When I press XF86AudioLowerVolume once, no information is displayed. However, If I press XF86AudioLowerVolume twice, "C-h k" indicates that I pressed "C-g".

I believe that this behavior is introduced in emacs-30, because this key works fine in the released emacs 29.1.

To reproduce, simply press the XF86AudioLowerVolume key  in "emacs -Q".

In GNU Emacs 30.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version

 3.24.38, cairo version 1.17.8) of 2023-09-16 built on XPS13
