feat: `ListEmptyState` and configurable `ListRowItem` prefix

[nextchamp-saqib]

Added empty state for list component.

emptyState: {
    title: 'No Query Created.',
    description: 'Create a new query to get started.',
    button: {
        label: 'New Query',
        variant: 'solid',
        onClick: () => (),
    },
},

Also configurable by slots

<ListView>
    <ListHeader />
    <ListRows />
    <ListEmptyState>
        <p>No pages to display.</p>
        <Button label="New Page" variant="solid" @click="() => {}" />
    </ListEmptyState>
</ListView>

Set default row height to 40px.

This ensures that the row height does not change if a row item prefix (like Avatar, or Indicator) is added to the list row item. It can be modified using options.rowHeight

Added configuration to define prefix/suffix and custom label for each column

{
    label: 'Label',
    key: 'label',
    width: 1,
    getLabel: ({ row }) => row.label,
    prefix: ({ row }) => <IndicatorIcon />,
}
