Cross language serialization for primitive types (#7711)

Browse Source 
* Cross language serialization for Java and Python

* Use strict types when Python serializing

* Handle recursive objects in Python; Pin msgpack >= 0.6.0, < 1.0.0

* Disable gc for optimizing msgpack loads

* Fix merge bug

* Java call Python use returnType; Fix ClassLoaderTest

* Fix RayMethodsTest

* Fix checkstyle

* Fix lint

* prepare_args raises exception if try to transfer a non-deserializable object to another language

* Fix CrossLanguageInvocationTest.java, Python msgpack treat float as double

* Minor fixes

* Fix compile error on linux

* Fix lint in java/BUILD.bazel

* Fix test_failure

* Fix lint

* Class<?> to Class<T>; Refine metadata bytes.

* Rename FST to Fst; sort java dependencies

* Change Class<?>[] to Optional<Class<?>>; sort requirements in setup.py

* Improve CrossLanguageInvocationTest

* Refactor MessagePackSerializer.java

* Refactor MessagePackSerializer.java; Refine CrossLanguageInvocationTest.java

* Remove unnecessary dependencies for Java; Add getReturnType() for RayFunction in Java

* Fix bug

* Remove custom cross language type support

* Replace Serializer.Meta with MutableBoolean

* Remove @SuppressWarnings support from checkstyle.xml; Add null test in CrossLanguageInvocationTest.java

* Refine MessagePackSerializer.pack

* Ray.get support RayObject as input

* Improve comments and error info

* Remove classLoader argument from serializer

* Separate msgpack from pickle5 in Python

* Pair<byte[], MutableBoolean> to Pair<byte[], Boolean>

* Remove public static <T> T get(RayObject<T> object), use RayObject.get() instead

* Refine test

* small fixes
