### Issue description

![1](https://github.com/godotengine/godot/assets/28705694/15c14c93-7ad7-425a-8fb0-bef841b75527)

It's not possible to start text selection on a SpinBox when it's unfocused.

Note: After a bit of digging in the code, I found that clicking on a SpintBox doesn't trigger `SpinBox::gui_input` no matter if it's focused or not. However, releasing mouse left button does trigger the function.

### Steps to reproduce

See the gif.

			selection_delete();
			set_caret_column(caret_column_tmp);
			insert_text_at_caret(p_data);
			grab_focus();
		} else {
			insert_text_at_caret(p_data);
			grab_focus();

		select(caret_column_tmp, caret_column);

				MessageQueue::get_singleton()->push_call(this, "_text_changed");
			}
			text_changed_dirty = true;
		}
		queue_redraw();
