check_compliance.py: Don't error out for internal test(e)dtlib errors

Instead of catching DeviceTreeCheck exceptions from test(e)dtlib.py all
the way up in main(), catch them in the DeviceTreeCheck test itself, and
report them with ComplianceTest.error().

That way, other tests (e.g. pylint) can still run and report to GitHub
when there are internal errors in test(e)dtlib.py.

Motivated by zephyrproject-rtos/zephyr#22255.
