Enable the computation and testing of GC metrics in ART's CMC collector.
These metrics were previously only enabled in ART's Concurrent Copying
(CC) collector; also enable them in the Concurrent Mark-Compact (CMC)
collector.
Amend test `HeapTest.GCMetrics` (in ART gtest `art_runtime_tests`) to
reflect this new behavior of ART's CMC collector.
