Unify the TCP feature with the TCP setting allowing both to be controlled
through the same Nimbus experiment.
Allow changing the default cookie policy to TCP based on the Nimbus experiment.
These are mostly mechanical changes to replace usage of `testHasValue`
with `testGetValue`.
`testGetValue` will now return `null` instead of throwing an exception
if no data is available.
After the update `TestCoroutineDispatcher`, `TestCoroutineScope` and
`runBlockingTest` are deprecated.
Instead of these new `TestDispatcher`, `TestScope` and `runTest` APIs are used.
Took the oportunity to also replace most of the `runBlocking` calls with the
new `runTest` specially designed for running coroutines in tests API.
* Feature flag for ETP cookie purging
* Strings for new ETP description
* Remove icons from ETP info screeen and add category for redirect trackers
* ETP policy factory tests
* Remove icons from ETP panel and add cross tracking allowed field.
* Remove icons on ETP panel. Add blocked category for redirect trackers to panel.
* Add margins to tracking protection settings
This is how we can apply the new test runner to remove duplication.

Where gsed is the GNU version of sed installed via homebrew. After
running these commands, I need to manually clean up the following files:
- FenixRobolectricTestRunner
- LocaleManagerExtensionTest
