[Lazarus] New IDE dialog to remove uneeded package dependencies

[Mattias Gaertner]

Hi,

I added a dialog to show unneeded package dependencies and delete
them. You can find it via the context menu of the package editor (right
click on a dependency) or via the package graph.

The dialog currently only checks the transitivity.
Maybe in future the uses sections can be checked too.

If you call it via the package graph it will work on all loaded
packages at once.
