Delete the workaround for handling warnings inside the loader

[omarahmed1111]

We have added a workaround for handling warning inside the loader in this PR. That workaround is needed for the deleting PI PR. However, this will be properly fixed in the new logger mechanism added by this PR. After the logger mechanism is merged, we should change the adapters entry-points that currently use UR_RESULT_ERROR_ADAPTER_SPECIFIC to report warning to use the new logger mechanism. We should attach deleting the workaround condition in the loader with the migration to use the new logger mechanism.
