Adds support for detecting Data Independent Timing (DIT) support which is available on Apple silicon (e.g. M1/M2/M3). This uses the `hw.optional.arm.FEAT_DIT` sysctl for detection. For more information, see: https://developer.apple.com/documentation/xcode/writing-arm64-code-for-apple-platforms#Enable-DIT-for-constant-time-cryptographic-operations

Note: I locally verified this was able to detect DIT on an M1 |
