media-video/pipewire: add 0.3.80

Note that this includes an extra backported patch to work with older webrtc
for now, although it's somewhat automagic based on if you have the (masked)
SLOT=1 installed for media-libs/webrtc-audio-processing.

+Subject: [PATCH] aec: support both webrtc versions
+
+Version 1 does not seem to be packaged in many distros and so they would
+need to revert the patch or disable AEC. Enabling both allows for things
+to move forwards gracefully.
