Subject: [PATCH 1/3] Simpler yet more useful handling of
KPIPEWIRE_FORCE_ENCODER
Previously, it always overrode the encoder type and profile.
Now just force a specific encoder by inlining the encoder selection
in the switch cases.
This means it's no longer possible to force a different encoder type
than the application requested, but it's arguably not that useful to
e.g. force VP9 if the application expects H.264 packets.
