Fix tab state UMAs on Android

Fix tab state UMAs on Android

Fixes the following issues:
- On launch, background tabs are recorded as Initial to Active transition.
- OnShow is called on the foreground tab right after launch, and is recorded as Active to Active transition.

This CL changes when background tabs are created on launch with the TabCreationState.FROZEN_ON_RESTORE, to start in the Inactive state.

Also removes reporting of same state transitions.

BUG=None
