bindings: Rename ConditionalFeature to OriginTrialFeature

Files introduced in https://crrev.com/487917 are still focusing on
only origin trials. It is confusing until it introduces other
conditional features.
Beside it, this name "ConditionalFeatures" is easy to conflict with
other methods in bindings code generation.

So this CL renames them to use OriginTrial.
