patterns: Rewrite evaluation engine (#306)

Browse Source 
* patterns: Rewrite most of the evaluator to mainly use polymorphism instead of just RTTI

* patterns: Fixed a couple of AST memory leaks

* patterns: Parse string operations correctly

* patterns: Various fixes and cleanup

* patterns: Implement primitive function definitions

Function parameters now need to provide their type in the definition

* patterns: Added function variable definition and assignment

* patterns: Added remaining function statements

* patterns: Added unsized and while-sized arrays

* patterns: Added multi variable declarations to functions

* patterns: Added std::format built-in function

* patterns: Allow passing custom types to functions

* patterns: Added attributes and new "format" attribute

* patterns: Use libfmt for std::print instead of custom version

* patterns: Remove unnecessary string compare function

* pattern: Fix preprocessor directives

* patterns: Fix unit tests

* patterns: Added cast expression

* patterns: Handle endianess in function parameters

* patterns: Added casting to different endian

* patterns: Added 'str' type for functions
