feat: OAS3 binary media type support (#4592)

* fix(validator-badge): resolve definition URLs against browser location

* use param as meta parameter if not found

* convert request body from Immutable if necessary

* show file upload for `format: binary` and `format: base64` jsonschema strings

* add `dispatchInitialValue` prop to JsonSchemaForm

* add optional subkey parameter to onChange

* add binary media type support to request body
