Add ability to debug dotnet Lambdas on arm64

## Problem

I get a message that says "The vsdbg debugger does not currently support the arm64 architecture. Function will run locally without debug." on my mac.

## Expected behavior

It would work the same as it does on an x86_64 machine.

Start by reproducing the reported dotnet Lambda debugging behavior on an arm64 Mac and compare it with x86_64 local debugging. Investigate the local Lambda debug path and the vsdbg architecture limitation; done means arm64 functions debug locally instead of falling back to running without debug.
