Add field_if_some setter for builders

Browse source 
This commit adds `_if_some()` variants for builder field setters.
The variants aim at improving usability when setting optional fields.
E.g. currently, we need to write something like:

```rust
let opt_value = ...;
let mut sb = gst::Structure::builder("test")
    .field("mandatory_field", "mandatory");

if let Some(value) = opt_value
    sb = sb.field("optional_field", value);
}

let s = sb.build();
```

With `_if_some()`, this can be written like this:

```rust
let opt_value = ...;
let s = gst::Structure::builder("test")
    .field("mandatory_field", "mandatory")
    .field_if_some("optional_field", opt_value)
    .build();
```
