Using new test infra

Summary:
# Context
In D87935980, new infra was introduced so that we can test all backends at once with a single test. We want to migrate existing tests to this new framework. 

# This Diff
Here, we migrate `quantized_linear_out` to use this new infra. When we ran 
```
buck test  fbsource//xplat/on_device_ai/Assistant/Jarvis/min_runtime/operators/test:test_quantized_linear_out_xtensa_Artemis_HiFi4_UT_v3 
```
we noticed that `op_quantized_linear_tie.cpp` doesn't have this fallback. Thus, we needed to add this fallback as well.
