insane: Split ERROR_QA into CHECKLAYER_REQUIRED_TESTS

We'd like to start requiring some set of checks are enabled for Yocto Project
Compatible Status and to pass yocto-check-layer. Start by splitting ERROR_QA
into two sets, the ones we think can be required and the ones we know have
challenges to implement (e.g. with prebuilt binaries).

To change the required list, the YP TSC would need to approve.
