Feat: Smartplaylist: Add dest_regen option for regenerating destination path (#5621)

Problem

1. When items are imported into the library in a don't copy-move mode
   (-C -M options), they will be registered inside the Beets database
   using their original paths. However, during subsequent processing
   (e.g., a convert operation), a path following the Beets path format
   can be generated.
2. When generating playlists using smartplaylist plugin, only the path
   registered inside the Beets database (the original path) can be use
   inside the output playlist. This block the compatibility with other
   plugins.

Solution

I added a a new optional configuration option known as dest_regen
(as well as its equivalent dest-regen on the CLI) to regenerate
items' path in the generated playlist instead of using the ones of the
library, just like a convert or a move operation would have done.
This operation will happen before the relative_to and prefix
options, which makes sense to do so and not in another order, otherwise
this new option (dest_regen)) would overwrite the desired behavior
of the other mentioned options (relative_to and prefix). It is
then helpful to generate playlists compatible with the convert
plugin.
