Final GSoC Part1 Update

Closes #2326.
This pull request contains updates for my Google Summer of Code (GSoC) project at the Final evaluation stage.

First PR (Midterm Evaluation Part): Changing the way the serialize, serialize_into and deserialize functions work
Third PR(Final Evaluation Part2): Adding support for JSON format

Feature Implementation

• Adding support for std::vector.
• Adding support for std::map.
• Adding support for std::complex.
• Adding support for std::set.
• Adding support for std::tuple.
• Adding support for std::queue.
• Adding support for std::stack.
• Adding support for std::pair.

Testing Functions (unit tests)

• Testing std::vector functions.
• Testing std::map functions.
• Testing std::complex functions.
• Testing std::set functions.
• Testing std::tuple functions.
• Testing std::queue functions.
• Testing std::stack functions.
• Testing std::pair functions.

Organization

• Seperate file for each type.
• type_traits.h for all the is_std_type.
• Move insert_back to a better place.
• Types_Implementation new directory.
• Clean serialization_fwd_decl.h.

To Be Done Before Merging

• Update byte_size for std::vector and std::map.
• Update byte_size for lua_table.
• Get rid of enigma_internal_sizeof_type and replace with byte_size directly.
• Replace enable_if<is_same_v<>> with is_type_t.
• Replace all r-value refs.

Adding new types

See Adding new types for the bytes format section here.

Sample game that is compatible with the AST_Generation branch

Balloon_Pop (It is the same game in the ENIGMA site but with modified scripts).
