use getConfiguration launch to read debug config

[brianignacio5]

Description

Read launch.json configuration using vscode.workspace.getConfiguration instead to avoid trail comma issues. Add initialBreakpoint as launch.json argument to define initial breakpoint to set in default initCommands.

Fixes #1253
Fixes #1259

Type of change

• Bug fix (non-breaking change which fixes an issue)

Steps to test this pull request

Say you have a launch.json with trailing comma like this:

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "gdbtarget",
      "request": "attach",
      "name": "Eclipse CDT GDB Adapter",
    }
  ]
}

If you click the debug button in the status bar ESP-IDF: Debug it was not working. With this PR, it should work now.

When you start a debug session, the program will stop by default in app_main. If you want it NOT to stop at app_main you should set:

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "gdbtarget",
      "request": "attach",
      "name": "Eclipse CDT GDB Adapter",
      "initialBreakpoint": ""
    }
  ]
}
