vl53l1x: Add test scenario for distance sensor.

[nedseb]

Closes #37

Summary

• Add YAML test scenario for VL53L1X ToF distance sensor with 16-bit register addresses
• Add **kwargs to FakeI2C methods to support addrsize=16 parameter
• Add machine.lightsleep stub in executor for VL53L1X mock compatibility

Test commands

# Mock tests (CPython)
python3 -m pytest tests/ -v --driver vl53l1x

# Hardware tests (STeaMi board)
python3 -m pytest tests/ -v --port /dev/ttyACM0 --driver vl53l1x -s

Pull request overview

Adds a new YAML-based scenario test for the VL53L1X ToF distance sensor and updates the CPython mock environment so the driver can run under the existing scenario test framework.

Changes:

• Added tests/scenarios/vl53l1x.yaml covering model-ID verification (mock/hardware), a mock distance read, and hardware/manual distance checks.
• Extended FakeI2C memory methods to accept keyword arguments (needed for drivers that pass addrsize=16).
• Stubbed machine.lightsleep in the mock executor to support VL53L1X driver initialization on CPython.

File	Description
tests/scenarios/vl53l1x.yaml	New scenario definition for VL53L1X mock/hardware/manual tests.
tests/runner/executor.py	Adds machine.lightsleep stub to improve MicroPython-API compatibility in mock mode.
tests/fake_machine/i2c.py	Updates FakeI2C method signatures to tolerate addrsize kwarg used by VL53L1X (16-bit register addressing).
