ESP32: Tests for machine.lightsleep/deep sleep

[hmaerki]

Feature Request

See: https://github.com/orgs/micropython/discussions/18394

Proposed implementation

• https://github.com/octoprobe/testbed_micropython

  • Add wireing to https://github.com/octoprobe/testbed_micropython/blob/main/src/testbed_micropython/tentacle_specs.py. I would use a relays to pull down pin 4 as described in https://github.com/shariltumin/wake_on_pin-esp32_sleep-micropython/blob/main/tests/deep_sleep_wakeon.py#L17C1-L17C58.
  • Define fallback to run the tests manually just on a naked ESP32

• https://github.com/micropython/micropython

  • Rewrite tests https://github.com/shariltumin/wake_on_pin-esp32_sleep-micropython to run unattended in testbed_micropython.
