fix: typing of ButtonPrimitive ref

[cahnory]

• add forwardConditionalRefs utility function
• add composeRefs utility function

[cahnory]

Here's how it was tested:

export const Test = () => {
  const unknownRef = useRef();
  const anchorRef = useRef<HTMLAnchorElement>();
  const buttonRef = useRef<HTMLButtonElement>();
  const bothRef = useRef<HTMLAnchorElement & HTMLButtonElement>();

  return (
    <>
      {/* Expected success */}
      <ButtonPrimitive />
      <ButtonPrimitive ref={undefined} />
      <ButtonPrimitive ref={buttonRef} />
      <ButtonPrimitive ref={unknownRef} />
      <ButtonPrimitive href="#" />
      <ButtonPrimitive href="#" ref={undefined} />
      <ButtonPrimitive href="#" ref={anchorRef} />
      <ButtonPrimitive href="#" ref={unknownRef} />


      {/* Would be better if it fails but success */}
      <ButtonPrimitive ref={bothRef} />
      <ButtonPrimitive href="#" ref={bothRef} />


      {/* Expected fails */}
      <ButtonPrimitive ref={anchorRef} />
      <ButtonPrimitive href="#" ref={buttonRef} />

      <ButtonPrimitive target="formId" />
      <ButtonPrimitive formTarget="formId" href="#" />
    </>
  );
};
