https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=275567



--- Description ---
- Switch to meson build (requirement since 3.24.36)
- Group BROADWAY, X11 and WAYLAND options into BACKEND multi option (at least
one backend needed to build)
- Docs, manuals and examples build are disabled by default (meson)
- ATK_BRIDGE option disabled for now as I can't find a config option for
it.[1][2]
- Organized Makefile vars to match gtk40 (for comparison)
- Patches that are not used by port were moved to files.OFF (temporarily)

NEWS: v3.5.6
The accessibility bridge code that exports accessible objects
on the bus is used by default (atk-bridge has been converted into
a library that GTK+ links against). To avoid the linking, you can
pass --without-atk-bridge when configuring GTK+.
