pipewire: split pulse and jack emulation out

Browse Source 
This splits PulseAudio and JACK emulation into separate outputs. Doing
so provides a number of benefits.

First it fixes pw-pulse and pw-jack. Prior to this they pointed to bogus
locations because the environment variables were not evaluated.
Technically fixing this only requires setting libpulse-path and
libjack-path to any absolute path not necessarily separate outputs but
it comes as a nice result.

Secondly it allows overriding libpulseaudio with pipewire.pulse in many
packages. This is possible because the new outputs have a more standard
layout.
