x11/libinput: Update to 1.11.3

Update x11/libinput to 1.11.3.
Switch to use the meson build system.
This adds a runtime dependency on python, since a bunch of libinput tools
uses python.
libinput tools, such as libinput-list-devices are now accessed through
bin/libinput.
Make wacom dependency an option (default to on). Make the gui tool
installation an option, default it to off.
Add upstream patches to detect epoll-shim, to work around issues with our
input.h headers, and to work around our lack of the versionsort() libc
function.

Remove old no longer needed patches.
