Bump HarmonyX to 2.16.0

[BennyDioxide]

Benefits: osx-arm64 (Apple Silicon) support, .Net 10

Problems to be addressed:
HarmonyX supports osx-arm64 via MonoMod/MonoMod#241, so MonoMod should be updated as well. But since they do a great amount of rewrite, things would be hugely complicated:

• The entire MonoMod.RuntimeDetour system has been rewrited, making detours no longer have OnDetour to hook on and PatchShield and InstancePatchFix thus stop blocking RuntimeDetour hooks.
• MonoMod.RuntimeDetour.DetourHelper is gone, DetourHelper::Pin and DetourHelper::GetNativeStart no longer works
• MonoMod.RuntimeDetour now bundles its own MonoMod.Iced through MonoMod.Core, making lots of conflicts

In newer MonoMod.RuntimeDetour, it appears to be new events too hook into, (Detour/ILHook)(Applied/Undone).
Unfortunately, the so called events are always called after the detour graph manipulation, so we'll have to manually patch the Apply methods.
Also, Detour is now gone, so we don't have to patch them as well.
