Add android browser tests w/o fieldtrial to ci/android-12l-x64-dbg-tests.

* This CL adds another integration test suites without field_trial_config. This will test the code path with the default behaviors;
* This CL also splits android fieldtrial tests into two separate suites: android and webview so they can be added into two different suites.
