For tgl+, the per-context setting of MI_MODE[12] determines whether the bits of a nested MI_BATCH_BUFFER_START instruction should be interpreted in the traditional manner or whether they should instead use a new tgl+ meaning that breaks backward compatibility, but allows nesting into 3rd-level batc
