Ble scanner (#976)

* Added ble_scanner component

* ble_scanner: time.h changed to ctime

* ble_scanner: Test added.

* ble_scanner: fixed code formatting.

* Removed duplicate binary sensor tests from test2 and test3 to decrease memory requirements.

* Removed another duplicate test from test2.yaml and moved stepper test to yaml3.yaml to reduce memory requirements of test2.yaml.

* Reverted the last stepper test change

* Moved some sensor tests from test2.yaml to test3.yaml to save memory.

* Moved ruuvitag back to test2.yaml as it requires component esp32_ble_tracker.

* removed apds9960 as it is duplicated
