[CFE] Fix leak introduced with "Add support for allowing imports of unsupported libraries" https://dart-review.googlesource.com/c/sdk/+/469240 (originally landed as https://dart-review.googlesource.com/c/sdk/+/465760) introduced a leak by saving assessors on dill libraries. Note that we _do_ save assessors on source libraries, but as these are converted to dill libraries (via the incremental compiler, i.e. in the setting where the leak happens) this is fine, but saving them on dill libraries means that these will retain access to old/invalidated/recompiled libraries and thus leak. The weekly bot has been red since the run on 2025-12-21. This CL fixes the issue by reporting the wanted errors when processing the import instead of later and can thus stop saving the data that causes the leak. It also moves when it's done so the error is issued for outline compiles too.

Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
