* Continuing from #1317 and its PRs for pistache server string enum code generation;
* A class that has an `anyOf` specification, in cpp side will have no members: in stead it should have a member having the type `classname_anyOf`
* Thus, Its `==` operator is not present or wrongly filled
* An string enum, should have a better usage, hence the `setEnumValue`
* this PR, is a brigde between `stringenumclassname_anyOf` and `stringenumclassname`
* `anyOf` specification is not just about `Enums`, so a better handling is needed from mustache templates, hence new template model parameter `isStringEnumContainer`
* PR fix: muttleyxd: `double semicolon`
* PR fix: wing328: `I think std::string is C++ only. What about adding x-is-string-enum-container instead in the postProcessModel operation in the C++ pistache server generator?`
* PR fix: wing328: `I think std::string is C++ only...` after fix get latest codes and then generate samples
