Minor refactor, added optional recursive dups for ast, ...

Browse Source 
- Added support for anonymous structs.
- Gave Token_Fmt::token_map its own static memory.
- Minor natvis fix for CodeBody
- Renamed ESpecifier::Static_Member to just Static (acts as a general use case) specifier option
- Setup the lex token array with a configurable arena allocator.

Two major things left before V0.3-4:
- Attribute and Module parisng support with base case test
- AST serializtaion strings get a dedicated slag allocator.

## Notes
The project has reached a sort of *alpha* state, all the current functionality works for the test cases but it will most likely break in many other cases.

@ -36,13 +36,12 @@ The project has no external dependencies beyond:
Dependencies for the project are wrapped within `GENCPP_ROLL_OWN_DEPENDENCIES` (Defining it will disable them).
The majority of the dependency's implementation was derived from the [c-zpl library](https://github.com/zpl-c/zpl).
When gencpp is in a stable state, I will make a C variant with the same feature set.
A single-header version will also be generated for both.
A `natvis` and `natstepfilter` are provided in the scripts directory.
***The editor and scanner have not been implemented yet. The scanner will come first, then the editor.***
A C variant is hosted [here](https://github.com/Ed94/genc); I haven't gotten headwind on it, should be easier to make than this...
## Usage
A metaprogram is built to generate files before the main program is built. We'll term runtime for this program as `gen_time`. The metaprogram's core implementation are within `gen.hpp` and `gen.cpp` in the project directory.

### *WHAT IS NOT PROVIDED*
* Lambdas
* Vendor provided dynamic dispatch (virtuals) : `override` and `final` specifiers complicate the specifier parsing and serialization. (I'll problably end up adding in later)
* Lang provided dynamic dispatch (virtuals) : `override` and `final` specifiers complicate the specifier parsing and serialization. (Its a todo)
* Suffix specifiers for functions (Ex: void() const ). Same reason as virtual/override/final missing for now.
* RTTI
* Exceptions
* Execution statement validation : Execution expressions are defined using the untyped API.
* Parsing support for module specifiers and attributes. (Its a todo)

# TODO
* Implement a context stack for the parsing, allows for accurate scope validation for the AST types.
* Make a test suite thats covers some base cases and zpl containers (+ anything else suitable)
* Finish support for module specifiers and standard/platform attributes.
* Make a more robust test suite.
* Generate a single-header library.
* Improve the allocation strategy for strings in `AST::to_string`, `Parser::lex`, and `token_fmt_va`
* Improve the allocation strategy for strings in `Builder`, `AST::to_string`, `Parser::lex`, all three can use some form of slab allocation strategy...
* May be in need of a better name, I found a few repos with this same one...
* Support module and attribute parsing (Marked with TODOs for now..)
* Suffix specifiers for functions (const, override, final)
