Add ability to use lists of already exported assets as exclusions on configurations

[Varneon]

I use a dedicated project for creating nature environments and it has anywhere between 50-100GB worth of assets, which is not viable to have included in the project for the final build.

I export the dependencies of the final scene using the exporter in order to make revisions easier, but exporting duplicates of already exported assets could be cut down by storing the export history of the assets.

Maybe have an option to toggle "export records" on the package configuration in order to keep track of already exported assets if duplicate exports are not desired.

The records of exported assets could be another scriptable object which stores the full path and GUID.
