Do not allocate with `new` expression for Ptr

[SomeRanDev]

This should cause error. Allocation should require explicit API function call.

class SomeClass {
    public function new() {}
 }
 
 function main() {
    final a: cxx.Ptr<SomeClass> = new SomeClass();
 }

That's correct! Although new call in C++ sometime act like anti-pattern. But this issue should be an article in FAQs or wiki best practices.

I'll document it. Even give details in the error message 👌
I don't know why I didn't do this from the start, unexpected new allocs are such a hassle. 💀
