tests: drivers: w1: add basic api test

This commit adds basic api tests for the w1 driver.

These tests mostly make sure that everything compiles without
errors. They expect a w1-bus configuration without any connected slave.
No bidirectional read/write tests are executed.
Send tests simply send without verifying the output,
and receive tests expect an idle bus(receiving only logical ones).
