cpu/esp32/gpio_ll: fix & cleanup 
- `gpio_ll_toggle()` now is race-free
- avoid using a look up table but branch to the two different registers
  in the `gpio_ll*()` functions
    - in most cases the GPIO port is a compile time constant and the
      dead branch is eliminated by the optimizer, making this vastly
      more efficient
    - some MCUs do only have a single port, in which case
      `GPIO_PORT_NUM(port)` is known to return `0` even if `port` is
      not known, resulting in one of the branch being eliminated as
      dead branch no matter what
    - in case it really is unknown at compile time which port to work
      on, the branch can still be implemented efficiently by the
      compiler e.g. using a conditional move; likely more efficient
      than fetching a value from the look up table.
