MediaPlayer: Fix playlist manipulation on x86_64

Fixes a problem on x86_64 with removing, shuffling, and moving
multiple playlist items.

Instead of casting directly between an array of addr_t and int32
values, an int32 array is filled manually. Commands are passed
BLists instead of int32 arrays.

Fixes #15737 #16698

* Changed the PlaylistItem interface to be hopefully more flexible. It can
probably still be improved.
* Renamed EntryRefPlaylistItem to just FilePlaylistItem.
* Moved the "move into Trash" and "restore from Trash" implementation into
FilePlaylistItem. Also added what's needed to allow Tracker to restore the
entry itself.
* Refactored everything to make Playlist use PlaylistItems instead of
entry_refs and all that entails...
* The transition to virtualize PlaylistItems is not complete yet in the
Controller, since it still uses BMediaFile there. But it's much easier to
change that now.
* Objects which keep a PlaylistItem around do correct reference counting, but
some commands could be simplified if they were using references as well. It
still should work correctly, though, if I didn't miss anything. It should also
fix theoretical situations of encountering out-of-memory while messing with
the Playlist leading to inconsistent state between Undo/Redo and then leaking
items because of that.
* Added the discussed change that MediaPlayer checks it's own supported types
before rejecting a file by super type. (untested)
* When importing playlist items, the currently playling item is better
maintained during Undo/Redo.
* Some debugging code added in MediaTrackAudioSupplier, no functional changes.
* Fixed a number of coding style issues and automatic whitespace cleanup.

* Added "Randomize" feature to Playlist window (Edit menu). It randomizes
either the selected items, or the entire list if nothing is selected.
* Small cleanups here and there.
