Migrate player list gui to scenario

Move modules/gui/player-list into exp_scenario/gui/player_list using the
new exp_gui element API, matching the other scenario guis.

- Store the selected player and action on the container's player data
  instead of a datastore, folding the datastore on_update reactivity
  into explicit setter functions
- Switch the actions config to injected accessor functions and the
  exp-gui_player-list locale namespace
- Add the locale section, register in control.lua, and disable the
  legacy module in the file loader
