* add low power modes
* add sleep to lsm gyro init
* bmx055 gyro has a 30ms wakeup time from deep suspend
* Sensord skip init values, first 500ms (#25775)
* remove lsm gyro sleep, handled by general cut

* change LSM6DS3TR(-c) gyroscope and accelerometer to interrupt
* add pthread for linking
* add interrupt collector thread to fetch in parallel to non interrupt based sensors
* change get_event interface to return true on successful read
* fetch sensor interrupts via gpiochip
* avoid sending empty messages (interrupt only, non interupt magn can leave a gap in the orphan block)
* add verifier script to sensor interrupts (sensor_data_to_hist.py)
* add/update sensord testsweet (test_sensord.py)
* add poll timed out check
* unexport interrupt gpio pins
* gpiochip on both edges, but skip falling edge if rising edge is detected, this is handled in the sensor as the status flag is checked if new data is availble
* add test to sensord to verify 100Hz interrupt frequency
* add sensor shutdown/low power mode functionality on sensord exit
* relax test, will be readded in the splitup PR
