option to generate schemas using 'allOf' to override default/etc rather than 'oneOf'

[hauntingEcho]

Due to not-great ecosystem support of allOf/anyOf/oneOf, it would be helpful to be able to configure which to use when generating a construct like

schema:
  default: ascending
  oneOf:
    - $ref: #/components/schemas/SortOrder

In particular, Swagger-UI only handles enums correctly if allOf is used, but currently oneOf is generated. The documentation for "AllowReferencesWithProperties" already mentions that "allOf/oneOf with $ref" may be used

This would resolve the NSwag issue: RicoSuter/NSwag#3645

edit: It looks like the relevant code is here

the piece of code you reference doesn't seems to fix the issue of the missing dropbox for the enum parameters (you linked this issue in there), it only applies to the models and not to the api parameters
