FR: Add check that simple uses of Objects.requireNonNull and Preconditions.check* use safe-logging

[carterkozak]

Uses of the following with constant-value strings (already validated by PreconditionsConstantMessage) and no parameters should be migrated to use safe-logging preconditions , which does not require changes beyond switching the method invocation:

Objects.requireNonNull(Object),
Objects.requireNonNull(Object, String),
com.google.common.base.Preconditions.check*(Object),
com.google.common.base.Preconditions.check*(Object, String)

[carterkozak]

Open question: do we want to error/warn on functions which do not provide a message? Moving to safe-logging won't provide additional data, but does provide some standardization.
