Summary:
Pull Request resolved: #35960

This fixes #35864

This feature allows using $Partial<Obj> in flow and Partial<Obj> in TypeScript based on the spec mentioned here: https://flow.org/en/docs/types/utilities/#toc-partial.

We currently only allow passing an Obj to Partial so

export type SomeObj = {
  a: string,
  b?: boolean,
};

export type PartialSomeObj = Partial<SomeObj>;

should work.
and also-

export type PartialSomeObj = Partial<{
  a: string,
  b?: boolean,
}>;

But not

export type PartialSomeObj = Partial<Partial<{
  a: string,
  b?: boolean,
}>>;

This can be improved in the future by a recursive unwrapping of the value inside the Partial annotation.

Changelog:
[General] [Added] - Allow the use of "Partial" in Turbo Module specs.
