DisplayConfig: Replace mode 'u' flags with 'a{sv}' property bag

Browse Source 
To be more flexible without having to change any D-Bus type signatures
in the future, replace the 'uint' flags value (currently determining
whether a mode is current and/or preferred) with a variant lookup table.

The keys 'is-current' (b) and 'is-preferred' (b) replace the existing
flags.
