Support Array parsing in events (#37142)

Summary: Pull Request resolved: #37142 This diff introduce support to parse arrays in events. We support parsing Arrays of: - Boolean - Double - Float - Int32 - String Enums - String - Objects - Arrays ## Changelog: [General][Added] - Add generic support for Arrays in Events parsing Reviewed By: dmytrorykun, RSNara Differential Revision: D45268779 fbshipit-source-id: 0c6eae65eb2b41ebf7b47a4cc3e0f0e5fa20d871
