Extend the wireplumber recipe to enable the session manager on all
plaorms and provide AM62D2 EVM specific audio initialization.
A set-audio-defaults.sh script is packaged to configure default audio
sinks and sources at runtime, managed by a dedicated systemd service
that runs after wireplumber starts.

Adding the whole ${bindir} folder to the package is not the standard, use ${bindir}/set-audio-defaults.sh and limit it to only am62dxx-evm.

Using systemd-udev-settle.service is not recommended [0]. Please use
appropriate `.device` dependency.
