Resetting the global state between runs was previously handled by a
RAII type, but the semantics of that type changed to remove this
behavior in [1].

This new name emphasizes that the field trial keys are only allowed
within the current scope. We already have test::ScopedFieldTrials that
can be used to ensure that the global field trials string itself is
isolated.

This new class implements the existing FieldTrialsView interface,
extending it with the verification functionality. For now, the
verification will only be performed if the rtc_strict_field_trials GN
arg is set.
Most classes extending FieldTrialsView today have been converted to
extend from FieldTrialsRegistry instead to automatically perform
verification.

For now, the run-time check will only be enabled if the
rtc_strict_field_trials GN arg is set.
In order to allow testing with imaginary field trial keys, two test
helpers have been added. It's a bit awkward to test these since the
field trial string is already global, hence the helpers are also
modifying global state. Tests must make sure this global state is reset
between runs. Things won't be an issue anymore when [1] has removed the
global string.

Calling InitFieldTrialsFromString modifies a global variable so we must
make sure that state is reset between test runs.

This renames the tests to also capture the expected outcome of the test
along with some minor code cleanups. Some tests have also been added or
extended to tests more invariants.

Create FieldTrials class for setting the field trials from a string
in a program. We can later e.g add a builder class where one
can add key/value pairs.
This class is supposed to replace
webrtc::field_trial::InitFieldTrialsFromString.
