Add support for array manipulation

[Archie-osu]

• Added an operator[] for non-const RValues
• Added const char* and std::string_view initializers for RValues that don't require YYTKInterface
• Added a warning for when there's unsupported functions right outside YYRunnerInterface's bounds
• Added API function GetArrayEntry for getting pointers out of arrays
• Added std::initializer_list support for inline initialization of RValue arrays
• Added a custom operator[] overload to CInstance and RValueobjects, allowing direct struct access
• Changed GetInstanceMember to return AURIE_OBJECT_NOT_FOUND for when accessing a non-existent struct member
• Added YYTK Shared headers define for easy version identification and comparison with YYTK's QueryVersion result

TODOs:

• [x] Test if GetArrayEntry actually works
• [x] Make documentation for GetArrayEntry
• [x] Test more games than just HoloCure and Sonic.exe
