fmt: fix optional_len or use_nul_termination being used by both array and elems

Browse Source 
```odin
My_Struct :: struct {
	names:      [^]string `fmt:"v,name_count"`,
	name_count: int,
}

main :: proc() {
	name := "hello?"
	foo := My_Struct {
		names = &name,
		name_count = 1,
	}
	fmt.println(foo)
}
```

Before: `My_Struct{names = ["h"], name_count = 1}`
After:  `My_Struct{names = ["hello?"], name_count = 1}`
