Description

Description

Factored out from #22794 and #16855. We should extend DV to cover the sideload key becoming invalid during operation in all possible states.

@andreaskurth and I discussed that this is not ultra critical (thus M5 rather than M4) but that it's still relevant because KEYMGR may clear sideload keys anytime it enters the invalid state / during an escalation. We should make sure this is covered sufficiently in DV to verify that KMAC does the right thing in this case.
