xmake-vscode: Windows: debugger not found on MinGW

Describe the bug

When attempting to debug a program using the xmake Debug button in the VS Code extension, we get an error message popup.

Error output

Unable to start debugging. Launch options string provided by the project system is invalid. Unable to determine path to debugger. Please specify the “MIDebuggerPath” option.

Info

The line that is causing the issue is:

https://github.com/xmake-io/xmake-vscode/blob/master/src/debugger.ts#L116

Putting the full path to gdb.exe in that field, eg:

miDebuggerPath: "C:/dev/msys64/mingw64/bin/gdb.exe",

… fixes it.

I do not know at this stage how to get the MinGW root from xmake in this extension so that we can append /bin/gdb.exe to it.
