Optimize: VM implementation "switch case" to "delegate array"

[Akeit0]

This PR is a large optimization.
NBodyBenchmark
.NET8 12ms -> 6.2ms
IL2CPP 81ms ->15ms

All changes are internal, so I think nothing is broken.

I have made some comments about the implementation that I am concerned about. I would appreciate it if you could check them.

[Akeit0]

I think I've finished revising them according to your comment.

[nuskey8]

I haven't looked into the implementation of LuaVirtualMachine in detail yet, so I'll merge it in as soon as I've checked it.

[nuskey8]

I have checked the VM implementation. It looks very good. The only thing that bothers me is that SetOperations is separated into a separate Operators class. Is there a reason for this?

Also, I would also be grateful if you could let me know if you have any references for this optimization.

[nuskey8]

There is a conflict due to the merge of #47, could I resolve this on my end?

[Akeit0]

Of course!

Considering that LuaVirtualMachine is a static class, and that using lambda expressions reduces readability and the visibility of exceptions, I use nested class.

No references available. I looked at the generated code and found that it was less efficient, so I adjusted it to generate the optimal code

[nuskey8]

I've resolved the conflicts and formatted the code.

If possible, could you please add comments to each step of the code? This will help me and other contributors understand the code properly.

@annulusgames
OK! Shall I leave the original async code in the comments?

[Akeit0]

Are these comments sufficient?
