Remaining work to transition to new unified `NativeFunction`

[RZhang05]

• Remove old natives using NewUnmeteredStaticHostFunctionValue and NewStaticHostFunctionValue. These use invocation or pass invocation around which is no longer supported in a NativeFunction. Refactor if possible.
• Remove Invocation.ArgumentTypes.
• Reduce NativeFunctionContext to smallest set, maybe replace with InvocationContext

Maybe also

• Switch uses of interpreter.HostFunction to NativeFunction
• Remove interpreter.HostFunction and interpreter.AdaptNativeFunctionForInterpreter
