ringabout 2d1412a2ea fixes #26015; Multiple definition error when using codegenDecl regression (#26018) 
fixes #26015

Fixes imported global variables with codegenDecl being emitted as
definitions instead of extern declarations.

A variable’s codegenDecl format should customize its definition in the
owning module. Other modules referencing the variable must emit a normal
declaration:

```c
extern NI variable;
```

After the variable-declaration builder refactor, genVarPrototype passed
Extern visibility to addVar. However, the sfCodegenDecl branch returned
before applying that visibility. This caused importing modules to emit
another tentative definition, resulting in duplicate-symbol linker
errors.

The fix restores the previous distinction between the custom definition
and cross-module prototypes. It also adds C and C++ regression coverage
for both direct access and access through an inline procedure.

follows up https://github.com/nim-lang/Nim/pull/24423
