Use likelihood attributes in NCE + Fix System Version + SVC improvements
The SVCs improvements are as follows: * Make SVC logs more concise for: * * `SleepThread` * * `ClearEvent` * * `CloseHandle` * * `ResetSignal` * * `WaitSynchronization` (Special case for single handle) * * `ArbitrateLock` * * `ArbitrateUnlock` * * `WaitProcessWideKeyAtomic` * * `SignalProcessWideKey` * Fix unintentional fallthrough into `yieldWithoutCoreMigration` from `yieldWithCoreMigration` in `SleepThread` * Return `result::InvalidState` when an unsignalled handle is reset in `ResetSignal` * Return `Result{}` (Success) in `CancelSynchronization` * Do not return `result::InvalidCurrentMemory` in `ArbitrateLock` as it's not a failure condition * Make `count` in `WaitProcessWideKeyAtomic` a `i32` from a `u32`, zero and all negative values result in waking all waiters
