Christian Brevik d4fb87b0b8 Add iOS 10 textContentType for TextInput
Summary:
Setting `textContentType` will provide the keyboard and system with semantic meaning for inputs. Should enable password/username autofill in apps running on iOS 11+ as demonstrated here: https://developer.apple.com/videos/play/wwdc2017/206/

Also gives you the ability to disable autofill by setting `textContentType="none"`: https://stackoverflow.com/questions/48489479/react-native-disable-password-autofill-option-on-ios-keyboard

Adding `textContentType` equal to `username` or `password`  should give you an autofill-bar over the keyboard which will let you fill in values from the device Keychain:

Setting the appropriate `textContentType` will fill in the correct value in the `TextInput`.
I have only been able to get this to work on device, and not simulator.

Usage:
```jsx
<TextInput
    value={this.state.username}
    onChangeText={this.setUserName}
    textContentType="username"
/>
```

```jsx
<TextInput
    value={this.state.password}
    onChangeText={this.setPassword}
    secureTextEntry={true}
    textContentType="password"
/>
```

To disable:
```jsx
<TextInput
    value={this.state.password}
    onChangeText={this.setPassword}
    secureTextEntry={true}
    textContentType="none"
/>
```

This will set `textContentType` to an empty string: https://stackoverflow.com/a/46474180/5703116
