/**
 * Composable for managing the v-model behavior of a prop.
 * It's behavior differs from the `defineModel` behavior, in that it will always prefer the bound value over the internal state.
 * This allows for better control over the component's state, e.g. a flyout can be kept open even when it was supposed to close.
 *
 * There is currently no way to differentiate between an explicitly bound `undefined` prop value (e.g. `<Comp :value="undefined" />`) and a implicit `undefined` from not defined prop (e.g. `<Comp />`).
 * Therefore for `null` or `undefined` values, the internal state or default value will always be used.
 *
 * For default values with non-primitive types, it's required to use a factory function that returns the default value to avoid mutating the former value.
 *
 * @example ```typescript
 *    const props = defineProps<{
 *        modelValue?: string;
 *    }>();
 *
 *    const emit = defineEmits<{ "update:modelValue": [string] }>();
 *
 *    const modelValue = useVModel({
 *      props,
 *      emit,
 *      key: "modelValue",
 *      default: "",
 *    });
```
