Mostly just cleanup and renaming of certain stuff (mostly in dependencies).
* Changed uw and sw to usize and ssize.
* Removed zpl_cast usage throughout dependencies
* No longer using GEN_DEF_INLINE & GEN_IMPL_INLINE
* header_start.hpp renamed to platform.hpp for depdendencies header.
* Number literals weren't getting properly lexed
* Fixes for compiler errors with Unreal Engine configuration.
* Support for "post-name" macros in parameters
* Support for variables initializing directly using constructor syntax.
* Explicitly added inline keyword to header inlines for compiling compile library in multiple translation units.
Interface adding has been adjusted to use ParentType->Next.
Using the AST_Class->Next was bad since that breaks the linked list a body AST would have used for traversal.
Adding the pragma once and includes the files broke compilation, still diagnosing why.
- Some string functions were moved to the cpp, still need to do some more evaluation of it and the containers...
- Added support for forceinline and neverinline to parsing (untested)
- Added support for specifiers in operator cast such as explicit, inline/forceinline/neverinline, etc.
- Before it only support const.
- Still need to support volatile.
- Forceinline was not supported at all for tokenization, fixed that.
Isolating large macros to their own directory (components/temp).
- Plan is to remove them soon with proper generation.
Added additional component files, separating the old data_structures header for a set of ast headers.
Header_end also had its inlines extracted out.
Necessary to complete the macro isolation.
ZPL parser dependencies were removed from the core library along with builder, its now generated in bootstrap as pare of making a gen_builder set of files.
Singleheader will be changed in next few commits to reflect this as well (By making builder deps and components a conditional option).
Tests are most likely all broken for now.
