spa: Add default: statements

Browse source 
This allows to use the library in projects that use `-Wswitch-default`
without any

 #pragma GCC diagnostic push
 #pragma GCC diagnostic ignored "-Wswitch-default"
 #pragma GCC diagnostic pop

This is useful as as the header is being pulled in via
pipewire/wireplumber headers into projects that might have this warning
enabled and would otherwise fail to build with -Werror.
