Support readOnly and writeOnly

[kenny-statsig]

Use Cases or Problem Statement

Swagger OpenAPI v3 supports readOnly and writeOnly indicators https://swagger.io/docs/specification/v3_0/data-models/data-types/#objects.
However it seems the codegen does not yet support these.

Proposal

Handle the readOnly and writeOnly attributes in the following way:

• readOnly -> "computed"
• readOnly & default -> "computed"
• readOnly & required -> "computed"
• writeOnly -> "optional"
• writeOnly & default -> "optional"
• writeOnly & required -> "required"
