It has potential to improve the speed if we want to append n false
Currently, we can only do `append_slice`.
```rust
#[inline]
pub fn append_slice(&mut self, v: &[bool]) {
self.values_builder.append_slice(v);
self.null_buffer_builder.append_n_non_nulls(v.len());
}
```
If we want to append n false, the first line code can be ignored, since it
only appends value if it is true
