rewrite asset operations to reduce allocations

• When raising AssetRequested, SMAPI now creates a single event args model and reuses it for each handler.
• There's now a single AssetOperationGroup per asset, which tracks the loaders/editors registered by every mod for that asset.
• The operation group's loader/editor lists are now used directly instead of querying them.
