DDSXTY14 — Need to add an ignore_enum_literal_names in TypeConsistencyEnforcement QosPolicy

The type assignability rules for Enumerated Types require knowledge of whether the literal names should be considered for assignability.

Right now this can only be configured when the type is declared using the @ignore_literal_names annotation. However in some cases it may be necessary to change this behavior at run-time for a particular DataReader.

To support this use-case it would be helpful to add a ignore_enum_literal_names field to the TypeConsistencyEnforcement QosPolicy
