[TS] sample with target: "best common type" problem

[bloadvenro]

sample({
  target: {} as Unit<{ a: string; b: string }>,
  source: {} as Unit<{ a: string }>, // should not let such assignment
  //////////////////////////////////////////////////////////////////////////////
  ///////////////// types of props below do not affect anything ////////////////     
  //////////////////////////////////////////////////////////////////////////////
  clock: {} as Unit<any>,
});

sample({
  target: {} as Unit<{ a: string; b: string }>,
  fn: () => ({ a: '' }), // should not let such assignment
  //////////////////////////////////////////////////////////////////////////////
  ///////////////// types of props below do not affect anything ////////////////     
  //////////////////////////////////////////////////////////////////////////////
  source: {} as Unit<any>,
  clock: {} as Unit<any>,
});

Last time we faced with the same problem in forward typings.

I'll add NoInfer<T> type suggested by Typescript comminuty and modify inference for each sample overload which includes target.
