Make Uno001 an error on Uno heads

### Describe the bug

It's easy to miss `Uno001` errors about something not being supported on Uno Platform during development (as the warning window is usually a mess and easy to ignore).

We'd like to have a nice way to better highlight these issues before they get hit in the CI when warnings turn to errors.

However, we don't want to disrupt early prototyping by having these be blockers from running code.

In this regard, we feel a good solution is to have a middle-ground.

If you run the UWP or Windows App SDK heads, nothing should change.

If you run a WASM head, then Uno001's will be flagged as errors instead of warnings, thus you'll need to fix them to continue testing on Uno.

This provides an easy path to test and prototype and then a way to check and bubble up these issues locally easily before submitting to the CI.

### Expected behavior

Able to detect Uno001 issues more easily.

### Help us help you

Yes, but only if others can assist.

Issue không nêu tên các tệp triển khai hoặc test, vì vậy hãy bắt đầu bằng cách xác định cấu hình build hoặc analyzer phân biệt các WASM head với các UWP và Windows App SDK head. Xác minh rằng Uno001 chỉ được coi là lỗi đối với WASM, trong khi các head khác vẫn giữ nguyên hành vi warning hiện tại.
