Component used: wear-compose
Version used: Alpha20

Close if intentional.

I'm using the same component in the list page, and then as one item in the detail page.  AppCard requires an onClick, and doesn't allow setting enabled = false.

So I'll have to duplicate the whole AppCard to make it look the same but not clickable.  It doesn't make sense for it to have a ripple and do nothing when clicked.

```
@Composable
public fun AppCard(
    onClick: () -> Unit,
    appName: @Composable () -> Unit,
    time: @Composable () -> Unit,
    title: @Composable () -> Unit,
    modifier: Modifier = Modifier,
    appImage: @Composable (() -> Unit)? = null,
    backgroundPainter: Painter = CardDefaults.cardBackgroundPainter(),
    appColor: Color = MaterialTheme.colors.onSurfaceVariant,
    timeColor: Color = MaterialTheme.colors.onSurfaceVariant,
    titleColor: Color = MaterialTheme.colors.onSurface,
    contentColor: Color = MaterialTheme.colors.onSurfaceVariant,
    content: @Composable () -> Unit,
) {
    Card(
        onClick = onClick,
        modifier = modifier,
        backgroundPainter = backgroundPainter,
        enabled = true,
```
