[jest] Fix enabled prop in buttons. (#3062)

## Description

Currently using `enabled` prop in our buttons doesn't work. Mocks are done using `TouchableNativeFeedback` and it has `disabled` prop instead of `enabled`. This PR changes mocked version of our buttons to handle `enabled` properly.

Fixes #2385 

## Test plan

<details>
<summary>Run the following test</summary>

```tsx
import { fireEvent, render } from '@testing-library/react-native';
import Mocks from '../mocks';

describe.only('Testing disabled Button', () => {
  it('onPress does not trigger', function () {
    const onPress = jest.fn();
    const { getByTestId } = render(
      <Mocks.RectButton testID="btn" onPress={onPress} enabled={false} />
    );
    const btn = getByTestId('btn');

    expect(onPress).not.toHaveBeenCalled();
    fireEvent.press(btn);
    expect(onPress).not.toHaveBeenCalled();
  });
});
```
