gak a47cc2a85c Migrate @Provides methods to @Binds methods where possible.
@Binds is a much more efficient way to delegate one binding to another in that:
  * The @Binds method does not need to be invoked
  * It does not generate an additional Provider implementation
  * An additional Provider does does not need to be instantiated
Future changes to Dagger's component processor will add even further benefits.

More information: []

ATTENTION REVIEWERS: This migration is being done with global approval.  Per-project approval is not required.

Tested:
    TAP train for global presubmit queue
