[ML] Update NNFWType name of TRIx NPU Series

SRNPU is an unofficial name of TRIx NPU series.
Update the name with the official name.
Fortuately "SRNPU" was first introduced with Tizen 6.5 releases.

We have decided to expose the official name of these NPU series of
TRIV and TRIA series, which are exposed via a common NPU-Engine
low-level driver: "TRIx-Engine".

Note that in some commercial products with TRIx NPU series,
the low-level drivers might be not available to applications.
In such cases, high-level drivers (with less hardware control)
that wrap the low-level drivers will be provided (e.g., VD-AIFW).
