utils: codegen: Make users depend on `controls.py` in mesonHEADmaster

Currently, modifying `controls.py` does not make those build targets dirty
that use a script that includes it (e.g. `gen-controls.py`) because meson
has no knowledge of this dependency. Add `depend_files` to each
`custom_target()` invocation to fix this.

Ideally it would be possible to attach this dependency to `gen_controls`,
`gen_gst_controls`, etc. objects themselves, so that repetition is
avoided, but this does not seem possible at the moment.
