[TTS] Update IPHs in fieldtrial_testing_config

Updates the IPH param settings in the testing config file to
add the Translations IPH and move the IPH parameters for Longpress
into their own experiment. This reflects the Finch config layout
we are planning, which gets around the limitation of having an
IPH for each experiment when they are both active.
