logic: index and store Java annotations

Browse Source 
* add annotation symbol kind
* add annotation_usage edge kind
* increment storage version
* record java annotation decls
* record java annotation member decls (as fields)
* update expected output of java sample project indexing tests
* add tests for recording annotations
* add annotation icon, annotation colors
* add new annotation node and edge types to legend
