ART: add GC live ratio metrics to GC performance

Record average GC live ratio (copied bytes over allocated bytes in
form-space), and GC count for both minor and major ConcurrentCopy GC,
and print both if DumpGCPerformanceOnShutdown is set.

Test: Run art with -XX:DumpGCPerformanceOnShutdown on some benchmarks.
