Unify queue multiselect look with playlist screen

[thornySoap]

There is already a multiselect look in the playlist screen, so the provisionally looking check boxes in the queue don't seem to be necessary in my opinion.
This is what I thought would work well (The screen record also includes the commits from #233):

I'm open for suggestions and improvements!

Hi, thanks! That what I had in mind to change in the multiselect haha! But then web should change the icon (since this is about selecting all and this isn't the current behavior) any suggestions of icon?

Edit: I didn't review all the files (still only on my phone and looking at diff/code on phone is horrible), but I had a few interrogations:

• You've created a new MediaDataListItem, was there no other possibility? What has changed so much? (And why not just change only the lines on the "old" one?
• I see you've used Animated visibility, which is a good idea! But I think it should be uniform. Maybe we should add it everywhere else?

What do you think about this?

Oh, I forgot to delete MediaMetadataListItemOld. I just used it for easier editing, it doesn't have any usages throughout the project, I'm going to delete it.

I see you've used Animated visibility, which is a good idea! But I think it should be uniform. Maybe we should add it everywhere else?

Where exactly do you mean? The only leftover thing to be animated in the queue that I coud imagine are the (dis)appearance of the selection checkmark and the (de)select all icon. Or do you mean in other screens?

But then we should change the icon (since this is about selecting all and this isn't the current behavior) any suggestions of icon?

There is an "select" icon on fonts.google.com/icons that may be suitable ...
