Phil Howard 45cb9b4444 rp2/machine_pin: Fix simulated open drain with more than 32 GPIOs. ...

Changes are:
- Refactor the open-drain macros, add GPIO_ENABLE/DISABLE_OPEN_DRAIN, and
  move them to `mphalport.h`.
- Only use `uint64_t` for the open-drain mask if there are more than 32
  GPIOs (saves code size).
- Ensure we're shifting a `uint64_t` by using 1ULL constants.
