Some intrinsic code cleanup. The args check is handled anyways in the parser. We use a generated array alongside to prevent generating the intrinsic multiple times instead of using static storage. Other various cleanups as well.

Implement [[eraseable]] attribute. When used with a function it instructs the AST (which than transfers logic to the IR) that the function (or variable) is potentially unused (verified by checking the read count). This than propogates through the IR and prevents the IR from generating both the definition and global/function. The intrinsics system uses this as well to prevent intrinsic functions from being generated unless they're used.

Constant fold intrinsics if their arguments are constant. TODO: reference count intrinsics such that they're not generated unless they're used, currently when an intrinsic can be folded-away it's marked for generation and makes it to the final output binary even though it isn't used.

Implemented smart intrinsic / builtin system. When you use trivial math functions like "pow", if they don't exist as a builtin, the compiler will implement its own versions, likewise, if a compiler builtin depends on a function that exists, it will use it, likewise if it doesn't it will implement it. If you explicitally use __builtin_ (prefixed) versions, the compiler again will select the best option it can, be it a combination of both builtins and compiler builtins, all compiler builtins, OR, all builtins (most performant).
