Add support to turbo module codegen for WritableMap type.

[lucaswitch]

Description

Currently there is no support to codegen return a specific data structure as WritableMap.

This is currently supported

For example on a Turbo Module with name "example".

type SomeType: {
  id: string 
}

export interface Spec extends TurboModule{
  someMethod(): SomeType[]; 
}

That should generate a should generate a turbo module method called "public WritableArray someMethod(){}" definition on Java Turbo Module.

This is not currently supported

type SomeType: {
  id: string 
}

export interface Spec extends TurboModule{
  someMethod(): SomeType 
}

That should generate a should generate a turbo module method called "public WritableMap someMethod(){}" definition on Java Turbo Module. But actually gives the following error building on js codegen task:

 nodes: [
    Node {
      type: 'TSTypeReference',
      start: 3645,
      end: 3667,
      loc: SourceLocation {
        start: Position { line: 117, column: 49, index: 3645 },
        end: Position { line: 117, column: 71, index: 3667 },
        filename: undefined,
        identifierName: undefined
      },
      typeName: Node {
        type: 'Identifier',
        start: 3645,
        end: 3667,
        loc: SourceLocation {
          start: Position { line: 117, column: 49, index: 3645 },
          end: Position { line: 117, column: 71, index: 3667 },
          filename: undefined,
          identifierName: 'SomeType'
        },
        name: 'SomeType'
      }
    }
  ]

I think maybe the Turbo Module codegen does not have support to non primitive types only supporting: number, fuction, strings, arrays and objects. But the codegen could generate a Java structure that could have type safety for named properties javascript objects, or just accept a WritableMap as return type.

Steps to reproduce

Declare a turbo module that implement this simple feature. Should crash on build time.

type SomeType: { id: string }

export interface Spec extends TurboModule{ someMethod(): SomeType }

Hi @lucaswitch, thank you for this issue. As far as I know, Codegen do support object types in TS and for Android.

Note that writeable map is not type safe as well, given that you still have to check the types in native code.

Not sure if was a problem on my development environment, gonna test it again soon. Have a nice week.
