Support readOnly, and writeOnly

https://swagger.io/docs/specification/data-models/data-types/

Read-Only and Write-Only Properties
You can use the readOnly and writeOnly keywords to mark specific properties as read-only or write-only. This is useful, for example, when GET returns more properties than used in POST – you can use the same schema in both GET and POST and mark the extra properties as readOnly. readOnly properties are included in responses but not in requests, and writeOnly properties may be sent in requests but not in responses.

type: object
properties:
  id:
    # Returned by GET, not used in POST/PUT/PATCH
    type: integer
    readOnly: true
  username:
    type: string
  password:
    # Used in POST/PUT/PATCH, not returned by GET
    type: string
    writeOnly: true

If a readOnly or writeOnly property is included in the required list, required affects just the relevant scope – responses only or requests only. That is, read-only required properties apply to responses only, and write-only required properties – to requests only.

@jetbrains-junie investigate the specification added in the issue, and investigate how it can be implemented in the typed module. DO NOT ATTEMPT TO FIX THE CODE. DO NOT CHANGE THE CODE. Instead write a proposal FIX.MD to fix the problem, so I can review and approve the changes before you attempt to implement it.
