[Feat][Java] Recording gap between C++ and Java library

[Thespica]

Is your feature request related to a problem? Please describe. Now, our Java library rely on C++ library. But with iteration of C++ library, there are some gap between those two library.

Recording these gap will help Java developers to fit these changes.

Use inherit to implement EdgesCollection

To fit this change:

• Remove 4 supper classes of EdgesCollection;
• Remove create function in EdgesCollection;
• Write a new factory function in util/GrapharStaticFunctions.java to create EdgesCollection, which maps ConstructEdgesCollection in C++;
• Add annotations for EdgesCollection:
  • For class: @FFIGen @FFITypeAlias @CXXHead
  • For return objects: @CXXReference or @CXXValue
• Modify related usage in test.

Refactor the C++ SDK with forward declaration and shared ptr

The main point that may affect Java SDK is using std::shard_ptr to manage info classes, thus the usage and parameters about info classes should have corresponding changes.

Additionally, it also relates to problems concerning memory management #285 , so we should design more for Java SDK about memory management.
