Remove unused class UsageInformationConsumer

The class was added in I2f9e71832 9fe25d21b ("Introduce dedicated
proguard usage-info consumer.", 2017-12-06) in which a new field
InternalOptions.usageInformationConsumer was added with type
StringConsumer.

It appears that UsageInformationConsumer has never been used in R8
(except in the file UsageInformationConsumer.java where it is defined).
