[DASH] Remove deprecated 'action_type' refs (sonic-net#3257)

What I did
For DASH_ROUTE_TABLE entries, change action_type references to routing_type references.

Why I did it
sonic-net/sonic-dash-api#20 deprecates action_type in DASH_ROUTE_TABLE in favor of routing_type to more accurately describe the field.

Any downstream repositories which build SWSS will see a deprecation warning for action_type and builds with -Werror set will not compile.
