samples/drivers: led_pwm: Fixes for device testing

Browse source 
Modify led_pwm sample in order to make it usable in device testing:
- Remove parenthesis from the logs as they prevent use of regex
- Add a harness_config multiline regex in order to enable verdict
generation
- Update README

For each PWM LEDs (one after the other): For each PWM LEDs (one after the other):
- turn on - Turning on
- turn off - Turning off
- increase the brightness gradually up to the maximum level - Increasing brightness gradually
- blink (0.1 sec on, 0.1 sec off) - Blinking on: 0.1 sec, off: 0.1 sec
