Implement blocklist and allowlist for debugger configuration for justMyCode

This is a feature request for breakpoint debugging - to add a new butting for “Step in into my code” in addition to current existing “Step in”. This is same as PyCharms (or) any Jetbrains IDE.

This would help conditionally choosing in which part should I need to step into standard library. so justMyCode is not helpful here - it either turns on or off the library debugging as whole.

If you don’t like it, then I would like to have allowlist (and blocklist) options to specify libraries I want to step into (or not) when justMyCode is set to false. I think java debugger for vscode has something similar to this.

@jahan01 We have this ‘allowlist’ and ‘blocklist’ in the debugger. But we haven’t yet exposed this. You can use the “rules” field to do this, but it is not final.

    {
      "name": "Python: Current File",
      "type": "python",
      "request": "launch",
      "program": "${file}",
      "console": "integratedTerminal",
      "rules": [
          {"path": "<glob pattern>", "include": true},  // Include or Exclude using a glob pattern or file name
          {"module": "module name", "include": true}, // Include or Exclude by module name
        ],
    },
