meson: use glslang --depfile argument when possible

This reduces the amount of manual dependency tracking developers need to
do. This is turned on if glslang >= 11.3.0 is used, or 11.9.0 on
Windows, but otherwise the status quo is maintained. This means I have
not removed any use of `depend_files`. We could make make these hard
requirements and remove the use of `depend_files` too.
