Angus Gratton 164c549248 esp32/machine_pwm: Restore PWM support for ESP-IDF v5.0.x and v5.1.x.
The cleanup in 548babf8 relies on some functions not available in older
ESP-IDF. Temporarily restore them, until we drop support for ESP-IDF <5.2.

PWM functionality should end up the same regardless of ESP-IDF version, and
also no different from MicroPython V1.23.
