media-sound/pulseaudio: Bump metapackage to 16.1, drop default USE daemon

All packages which need real pulseaudio daemon (e.g. need extension modules
which are only implemented for real pulseaudio daemon, or just work with real
pulseaudio daemon only) already depend on media-sound/pulseaudio-daemon as an
alternative to media-sound/pulseaudio[daemon].

Drop default USE +daemon from metapackage to allow cleaning up
media-sound/pulseaudio-daemon if USE daemon is not set by user.

Client libs package media-libs/libpulse will still make sure that one
of available pulseaudio server implementations is installed, but will
not enforce any particular choice.

To change pulseaudio server implementation to pipewire make sure
neither media-sound/pulseaudio nor media-sound/pulseaudio-daemon
are in the @world and USE daemon is not set for media-sound/pulseaudio,
then set USE sound-server for media-video/pipewire and update as usual:

    emerge -avtuDU @world

To change pulseaudio server implementation to pulseaudio-daemon
remove USE sound-server from media-video/pipewire and update like this:

    emerge -avtuDU --oneshot @world pulseaudio-daemon
