ci(cmakev2): enable buildv2 CI testing

A new pytest_buildv2_system job has been added to execute selected tests
from the existing test_build_system test suite. Currently, only the
test_non_default_target.py is enabled. The ultimate goal is to run most
of the build system tests with buildv2. This should help ensure
compatibility between IDF build system v1 and v2.
