Update the Now Playing View

So that it looks a bit more like the mockups at https://gitlab.gnome.org/Teams/Design/other-app-mockups/-/blob/master/plattenalbum/layout.png?ref_type=heads.

Note that the queue has been moved to a new page, and can be accessed by clicking the button in the top.

Note that it's not yet 1:1 conformant to the mockups, but we are getting there.

I'm not sure if this should be a goal. In #132 we discussed the new layout and I pointed out that I'm not a fan of this approach with an extra playlist view for several reasons.

Besides in the current state of this PR it is very hard and unintuitive to get to the playlist when the player is collapsed. And there is no shortcut for that either.

Ohhhh, I'm sorry I didn't see this issue previously. I understand your concerns.

Those can be fixed later, after we figure out the design decisions.

I have a suggestion though: Would it be useful to use an Adw.ToggleGroup to quickly switch from the now playing view to the queue and lyrics.

This is how I'm currently doing it in Muzika:

Now playing	Queue	Lyrics	Related

But in Muzika on desktop I use a bottom bar, like this, so it's a bit different.

I think this is too complex. What is the issue with having the queue always visible?
