native operators overload can return arrays

[YashasSamaga]

Issue description:

Native operator overloads can specify an array return type. They should have the same semantics as non-native operator overloads. The compiler fails to diagnose it.

Minimal complete verifiable example (MCVE):

This compiles:

native Float:[10]operator+(Float:a, Float:b) = 0;
main () { }

This doesn't:

Float:[10]operator-(Float:a, Float:b) { }
main () { }

Workspace Information:

• Compiler version: 3.10.10
• Command line arguments provided (or sampctl version): pawncc main.pwn
• Operating System: Ubuntu 20.04

[Daniel-Cortez]

This doesn't:

Float:[10]operator-(Float:a, Float:b) { }
main () { }

This is because return array sizes are only valid in new-style function declarations that start either from keyword forward, or native. For example, this code

forward Float:[10]operator-(Float:a, Float:b);
main(){ }

would compile as well.

I think the real problem here is that operators aren't actually supposed to return arrays at all, and the compiler doesn't diagnose this. Fixing this shouldn't be hard.
