Set torch.backends.cudnn.enabled to false when testing accuracy (#94363)
Summary: It looks like setting torch.backends.cudnn.deterministic to
True is not enough for eliminating non-determinism when testing
benchmarks with --accuracy, so let's turn off cudnn completely.
With this change, mobilenet_v3_large does not show random failure on my
local environment. Also take this chance to clean up CI skip lists.
