Allow multiple tasks for command_webview

[jpelgrom]

Summary

'Fix' #3343 by allowing command_webview to create multiple, new tasks. This allows launching the webview to work reliably irrespective of how the app was originally started.

While this behavior may not be perfect in my opinion (you end up with hidden tasks which can be unpredictable), all app features that allow you to navigate to a specific page the webview such as shortcuts, tapping on notifications, device controls long press, etc. use this to reliably load the frontend with a specific page. Different behavior for this specific feature (which as a result didn't always work) doesn't make a lot of sense.

Docs don't mention anything about tasks/recents so let's not complicate things

Any other notes

Based on these specific reproduction steps, without this change:

• If the initial task was from the launcher, it seems to create a new activity (which will load the page)
• If the initial task was from command_webview, it seems to bring the existing activity to the front and that's it

There must be something here with task stacks/affinity different for launch vs webview as the 'root' that allowed it to work without requiring the multiple tasks flag. I've also tried checking the intent extras in onNewIntent for the second point, but it didn't call the function.
