Upgrade to .NET 9 and OTAPI Static Hooks for ARM64

[SignatureBeef]

This PR aims for the following:

• Target frameworks & workflows updated to net9.0
• OTAPI and other packages updated
• Moved to generated OTAPI static hooks, making MonoMod RD optional/supplemental (though, OTAPI.Runtime.dll is still included for those still utilising it)
  • Note: File scoped namespaces was utilised, which is why the diff is more than expected.
• Expanded workflow to test each platform
• Reduced OTAPI/ModFw console outputs (e.g. no tile ctor print, short version codes etc)

Considerations that may flow through to a TShock PR (or sooner if desired):

• OTAPI Static Hook namespace naming preferences e.g. HookEvents.* vs MonoMod RD On.*
• OTAPI Static Hook EventArgs property naming preferences e.g. ContinueExecution, HookReturnValue
• If any extra static hooks are needed, current list includes most methods from the following Terraria types:
  • Main, Item, NetMessage, Netplay, NPC, WorldGen, Chat.ChatHelper, IO.WorldFile, Net.NetManager, Projectile, RemoteClient, Liquid, Program.
• Apple Silicon / ARM64 testing
• Plugin updates: at the moment should just be a matter of ticking up to net9.0, and matching dependencies/updating

I have not tested the changes in game, however, the code changes look good. Thank you for working on this
