Split statistics module into :api and :impl (#4662)

Task/Issue URL:
https://app.asana.com/0/1205648422731273/1203121956327036/f

### Description

This PR splits the existing statistics module into statistics-impl and
statistics-api modules.

### Steps to test this PR

No behavior changes are expected. For smoke testing:
- [x] Check if the app is still sending pixels.
- [x] Create a crash and check that the corresponding pixel is sent.
- [x] Create an ANR and chcek that the corresponding pixel is sent.

### No UI changes
