Add an allowlist/denylist for browser sourcemap locations

Describe the bug
I'm debugging a React app in msedge. Instead of launching localhost, I'm launching teams.microsoft.com since my app will be loaded in Teams (iframe to localhost).
The issue is, if I set any breakpoint before launching, the whole browser gets slow and loads for several minutes.
But when there's no breakpoint, or set after page launched, the browser acts as normal.

To Reproduce
Steps to reproduce the behavior:

1. Create react app npx create-react-app my-app
2. Open the app in VSCode
3. Add launch.json

{
  "version": "0.2.0",
  "configurations": [
      {
          "type": "msedge",
          "request": "launch",
          "name": "Launch Teams",
          "url": "https://teams.microsoft.com/_#/l/app/",
          "webRoot": "${workspaceFolder}/src",
          "trace": true
      }
  ]
}

4. Set breakpoint
5. Debug
