Make WebGPU NVIDIA compat non-experimental

Makes the WebGPU compat suite non-experimental on Linux NVIDIA builders.
These tests are relatively stable at this point, and having them as
experimental messes with the autoroller's ability to automatically
create suppressions for failing tests.

Submitted with No-Try due to unrelated failures blocking
submission.
