Introduce BlazeInterners, a Blaze-specific wrapper around Guava's Interners that makes an appropriate call to Interners.InternerBuilder#concurrencyLevel.

For current readers of this CL, I used this class everywhere in the Blaze codebase.

For future readers of this CL, this class should be used to create an Interner in the Blaze codebase.
