Revert "DO NOT MERGE: Delete com.android.cronet from base_system. am: 8640960329"

This reverts commit 14199b7a933491f83dfed72ef8c6b84ce3e4a449.

Reason for revert:
Rollback the stuff which has been removed
due to "remove cronet for R" to keep the intermediate branches
synced between {aosp, internal} master
