tests/i915/gem_pxp: Verify execbuf fails with stale PXP context after teardown
Add a subtest to verify that reusing a stale protected context
in a gem_execbuff after a teardown fails with -EIO error because
it's banned. Trigger the teardown via the pxp invalidation
debugfs that simulates a HW teardown IRQ.
NOTE: The end-to-end architecture requirement includes that
any break in the links of the PXP sessions needs to trigger a
full teardown and the application needs to be made aware of that
allowing it to re-establish the end-to-end pipeline of buffers,
contexts and renders again if it chooses to. This stricter
behavior targets only contexts created with PXP enabled.
