Send intent to let calling app show UI safely without interfering the bugreport/screenshot generation.

- Calling app needs the intent from platform to show UI safely without interfering the bugreport/screenshot generation.
- Currently IncidentCompanionService can only send the intent to app of personal profile when there is work profile.
- But calling app may be from work profile.
- So change to use BugreportManager to send the intent to calling app.

BUG: 153809412
Test: Flash, press bugreport shortcut and confirm calling app of work profile can receive the intent.
