## Is your feature request related to a problem?

We currently load the "time conversion bins" funnel view [in two steps](https://github.com/PostHog/posthog/blob/cfd7e586ac144a0fb6c18f90a1657db9897d033a/frontend/src/scenes/funnels/funnelLogic.ts#L164):

```js
const result = await pollFunnel<FunnelStep[] | FunnelStep[][]>({
    ...apiParams,
    refresh,
    // Time to convert requires steps funnel api to be called for now. Remove once two api's are functionally separated
    funnel_viz_type:
        filters.funnel_viz_type === FunnelVizType.TimeToConvert
            ? FunnelVizType.Steps
            : apiParams.funnel_viz_type,
})

if (filters.funnel_viz_type === FunnelVizType.TimeToConvert) {
    const binsResult = await pollFunnel<FunnelsTimeConversionBins>({
        ...apiParams,
        ...(refresh ? { refresh } : {}),
    })
}
```

## Describe the solution you'd like

I'd like to make just one query. This makes caching dashboard results much easier.
