Add tests for modbus binary sensor (#40367)

Browse source 
* Add test coverage of binary sensor.

Update conftest to be generic.

* Pass total config structure to run_base_test.

Simple devices like sensor/switch do only have one entry in the
dict array, whereas e.g. switch have multiple entries.

* Use STATE_ON / _OFF for binary_sensor test.

* Update coveragerc

Only exclude files that uses a third party library.

* Remove modbus/* from coveragerc

* Remove modbus from .coveragerc

* Update .coveragerc
