Add Debugger Configuration for Running PXT Binary from VSCode

[nedseb]

We need to add a configuration to the makecode-steami project to enable the use of a debugger for launching the PXT-generated binary directly from Visual Studio Code. This feature will allow developers to debug their MakeCode libraries more efficiently, improving the overall development experience.

The goal of this issue is to provide a seamless debugging setup integrated with VSCode, allowing:

1. Direct Launch of PXT Binary: Set up the necessary configuration files (launch.json and others) to enable VSCode to launch the binary directly.
2. Breakpoint Support: Allow developers to add breakpoints in the MakeCode source and control the debugging flow.
3. Improved Developer Workflow: Simplify the process of testing and troubleshooting the code by making debugging accessible within the IDE.
