Android Auto: Make homepage similar to CarPlay

### Description

At the moment, the UI of the Android Auto version is different from CarPlay. To access features like Filters, you need to press the ... button, then access Filters. This can be a bit of a safety issue since a user would need to press a lot more buttons.

On Android Auto, we show 'Podcasts', 'Downloaded' and 'In Progress' as the 3 main menu items. On Apple CarPlay, we have 'Podcasts', 'Filters' and 'Downloaded'.

I think the CarPlay menu items should also be shown on Android Auto.

### Step-by-step reproduction instructions

1. Open the Pocket Casts app on Android Auto, view the UI
2. Compare this to what you see in Apple CarPlay

Start by comparing the Android Auto homepage with the existing Apple CarPlay menu described in the issue, focusing on how the three main menu items are defined. Done means Android Auto presents Podcasts, Filters, and Downloaded as its primary items and Filters no longer requires opening the overflow menu; verify the result in Android Auto and compare it with CarPlay.
