docs: Adds EntitySet V4 annotation for current extension if extension value is equal to
  the given non-default value. Depending on bDeepCopy the annotation will be merged
  with deep copy.
  @param {object} o
  any object
  @param {object} oExtension
  the SAP Annotation (OData Version 2.0) for which a V4 annotation needs to be added
  @param {string} sTypeClass
  the type class of the given object; supported type classes are "Property" and
  "EntitySet"
  @param {string} sNonDefaultValue
  if current extension value is equal to this sNonDefaultValue the annotation is
  added
  @param {boolean} bDeepCopy
  if true the annotation is mixed in as deep copy of the entry in mV2ToV4 map
