zephyr: test: migrate drivers test to twister

1. Move the common test logic to drivers/common with its own
   CMakeLists.txt
2. Move the drivers test suites to drivers/default with its own
   CMakeLists.txt
3. Add a Kconfig for each suite that can enable it, use Zephyr's
   add_subdirectory_ifdef to control which suites get added to the
   biary and verify that at least 1 suite was added.
4. Add a check for ZMAKE_PROJECT_NAME to still allow zmake commands
5. Add testcase.yaml which runs all the tests
