Use consistent perfmark lib alias in grpc

grpc-java-okhttp links against the perfmark lib. Update
grpc-java-core-internal to use this target, rather than
perfmark-api-lib. These libraries are effectively the same
in terms of contents, but only perfmark is a blessed apex
dependency, and using the same alias ensure consistent
static and dynamic linkage when using R8.
