[NPU] Fix ze_loader dependency (openvinotoolkit#26157)

### Details:
Commit ad4eb09 introduced dynamic loading of ze_loader so that it is
loaded only when really needed.
Recent changes in `ZeroRemoteTensor` caused NPU plugin binary to import
from ze_loader directly.

This commit should fix that and the NPU binary should have no longer
dependency on ze_loader.
