bug#52685: 29.0.50; Horizontal scrolling doesn't work when compiled with pgtk

[Andrey Listopadov]

After PGTK was merged I've compiled Emacs with the required switch.  The
first thing I've noticed was that --with-xinput2 has no effect when
--with-pgtk switch is supplied, so I've removed it.  I'm not sure if
this is intentional or not.  The main issue now is that horizontal
scrolling with a touchpad no longer works for me. All horizontal events
are registered as mwheel-down events.

In GNU Emacs 29.0.50 (build 2, x86_64-pc-linux-gnu, GTK+ Version
3.24.30, cairo version 1.17.4)
