rBf9113c4be836: Assets: add global `bke::AssetLibraryService` class

Summary

Add blender::bke::AssetLibraryService class that acts like a blendfile-scoped singleton. It's allocated upon the first call to BKE_asset_library_load and destroyed in the LOAD-PRE handler.

The AssetLibraryService ensures that edits to asset catalogs are not lost when the asset browser editor closes (or even reloads). Instead, the AssetLibrary pointers it owns are kept around as long as the blend file is open.

Outside of the scope of this patch: handling the case when the blend file is saved (or saved to a different directory).

Didn't dig too deep, things look as I'd expect them.

One thing that I'd argue - and we could (re)evaluate and change this later on too - is that this shouldn't be named AssetService. I'd prefer AssetSystem, or similar. "Service" for me is something that does one well defined job for me. It doesn't hold own data storage except some smaller stuff it needs for internal work (or if the service is about actually managing some storage). What we design here is the entry point to something bigger than that, something that can contain many services and storage facilities. For me "System" is just much more appropriate.

I agree AssetService is not that good a name. I renamed it to AssetLibraryService, as its purpose is to serve AssetLibrary pointers to the rest of the world. For me the "System" is the bigger whole, comprising of all the asset-related code.
