fix(react-utils/createPolymorph): allow components to set displayName

[maeertin]

createPolymorph returns the original render function at runtime, so React components created by it can already have displayName assigned. Its TypeScript return type only described the callable signature, however, valid assignments such as Button.displayName = 'Button' to fail type checking. This change exposes the optional property in the public type and adds regression coverage.
