nixos/pulseaudio: make daemon.conf configurable (#20888)

This adds pulseaudio.daemon.config, which is a set of keys to values which are directly translated to keys and values of pulseaudio's daemon.conf, e. g. hardware.pulseaudio.daemon.config = { flat-volumes = "no"; } becomes flat-volumes=no in pulse/daemon.conf.
