monitor-config-manager: Use monitor match filters to create config

Browse source 
Factorize the creation of a configuration inside one function that looks for
the primary monitor and the other monitors using the matching rules and
dispose them according to the chosen policy (checking if the result is valid
when using the suggested positioning).
