Run settings earl grey tests on the unified consent enabled bot

This CL updates the setting earl grey test to run with unified consent
feature enabled. It also adds the settings earl grey tests to the list
of tests that are run on the unified consent enabled bot.

Note: There are a significant number of earl grey tests for settings,
so this CL will significantly increase the time it takes to run the tests
on the ios-simulator-full-configs bots. However the unified consent enabled
bot is temporary and the current plan is to remove it once unified
consent feature is enabled by default.
