test(ci): retry Windows teardown EPERM and restart evaluate misses (#17780)

Restart-survival polls treated a recycled renderer as a hard failure.
Wrap those evaluates so "Execution context was destroyed" is a pending
miss. Windows package-lane teardowns after a force-kill used rmSync
with force:true only, which does not absorb EPERM; put them on the
shared maxRetries:8 policy.
