default-session-manager is only used in the pw-uninstalled.sh developer
script. c25cec230c added the ability to
use the system-installed wireplumber but other than that this option is
largely superfluous.
Drop it and pick whichever the first entry to session-manager is. For
the vast use-case of either MS or WP this will just work fine and for
the niche case of building both SMs one just needs to make sure the
order is as desired.
And in the case of no session manager, the config line to start the SM
is now commented out.
Some distributions set --auto_features=enabled which messes with the
internal logic of the build system when features are used for other
purposes than pure dependency control. The only solution is to either
avoid the value auto or change the type of the option to non-feature.
This commit does the later by replacing -Dmedia-session, -Dwireplumber
and -Dsession-manager with the new -Dsession-managers array and
-Ddefault-session-manager combo options.

FreeBSD ports tree does not have alsa-lib >=1.1.7 yet,
build the newer one locally in CI until a newer version
of alsa-lib lands to the FreeBSD ports tree.
