[Misc] Fast serialization

[sandlerwang]

Summary:
Introduce fast serialization feature.
This feature can be enabled by -Dcom.alibaba.enableFastSerialization=true. Porting from dragonwell-project/dragonwell11@bfdc905 and the origin author is lei.yul.

1. Create a ClassResolveCache to reduce calls to Class.forName(String)
2. Cache latestUserDefinedLoader(): The loader can be safely cached inside the ObjectInputStream class, once custom readObject() methods are invoked, the cache will be invalid.

For simple data objects, we can observe a 26% performance improvement. See com.alibaba.bench.java.io.ObjectInputStreamTest.

Test Plan:
Add one more round for ObjectInputStream jtreg test with -Dcom.alibaba.enableFastSerialization=true
