Now all fft tests work but the CI / Test (macOS, Apple sillicon) check is not passing.

[MauroToscano]

There's a bug with how the CUDA and Metal is used. It's assuming that if the feature is enabled, it can run with CUDA or Metal. As a quickfix, you can add this in the relevant tests#[cfg(not(feature = "instruments"))]. We should fix this in more general way, even if the feature is not enabled it could backoff to the CPU version, but it's not critical.
