[gtk/gtk-3-24-meson: 39/95] meson: Build the input modules



commit 5e8edec25434f475dbca04eba84fc621810e7c37
Author: Chun-wei Fan <fanchunwei src gnome org>
Date:   Mon Mar 25 17:33:03 2019 +0800

    meson: Build the input modules
    
    Build the input modules for GTK+, either as modules or built directly
    into GTK.  Also provide a configure option to build the specified
    immodules, or all, or the backend immodule(s) or none of the immodules
    into GTK.  Note that for Visual Studio all immodules are built into
    the GTK DLL by default, like what is done in the Visual Studio projects.
    
    Note that building the backend immodules for Quartz, X11 and Wayland are
    currently untested.
