App latency test migration.

Migrate the existing app latency test to a new solution from Project Fi team.
The main change on this new solution is that the data collection part is done by Primes now.

Also, a few changes has been made on DialerPrimes class and a new Dialer variant dialer_release_test has been created.

The benefits of using primes to collect data are:
1. latency tests dont need to insert lines of code to track latency in dialer codebase
2. be able to collect data on any variants with or without Proguard
3. latency tests now only contain ui interaction to trigger scenarios on which we want add measurements
4. share the same logic with primes on production so that data from testbeds and normal users are comparable.
5. easier for anyone to add interesting data entries.
