commands: add generic option -> property wrapper

Add mp_property_generic_option(), a property function that can be used
for generic option-based properties that do not require any action
beyond manipulating the value of the option variable. Currently it
directly implements GET and SET, plus STEP_UP for "choice" options
only. Use it to add a property for -pts-association-mode (not
particularly useful in normal use, but serves as a test).
