M1 Mac (Apple Silicon): AWS SAM Golang lambda debugging does not work

**Desktop (please complete the following information):**

- OS: macOS BigSur 11.5.2 (M1)
- VS Code version: 1.16
- AWS Toolkit extension version: 1.29.0
- AWS SAM cli version: 1.31.0
- Go version: 1.16.8 (also tried this with the latest 1.17.1, but has the same issue)
- vscode-go version: 0.27.2

### How to get my AWS SAM initiated local debugging of lambda's written in Go working?

**Summary of the problem**
After creating a plain vanilla AWS SAM application with `sam init` for `golang`, and then using the code lens to create an AWS SAM template file based debug configuration, I get the following error when trying to debug the lambda code. Running the code without debugging works.

From the output listed above, it seems to me that when using the debugger, it thinks that the function is not implemented.

**could not launch process**: fork/exec /var/task/hello-world: **function not implemented**

Running the above lambda from command line with `sam build && sam local invoke` works.

**Other considerations**

- Go debugging works for vanilla go apps (non lambdas)
- Go lambdas run successfully with `sam local invoke`.

**Steps to reproduce**

1. Create a new AWS SAM application using Go with `sam init`.
2. Select the `Hello world` template.
3. In the main.go file, create a debug configuration from the code lens provided by the AWS Toolkit and associated with the handler.
4. Set a breakpoint and start debugging.

Start with the generated debug configuration from main.go and the AWS SAM template, then compare the Toolkit's debug launch path with the working `sam build && sam local invoke` flow. Investigate the Delve startup output and the `/var/task/hello-world` launch failure on M1. Done means the generated configuration can debug the Go Lambda successfully while ordinary local invocation continues to work.
