feat(pack): add active field to PackChanged event data

Browse Source 
Problem: Inside `PackChanged[Pre]` callbacks it might be useful to tell
  if the affected plugin is active or not. It is already possible via
    extra `vim.pack.get({ 'plug-name' })[1].active`, but it is not quite
    user-friendly for something that might be needed frequently in real
    world use cases.

Solution: Supply extra `active` event data field.
