[onert] Fix compilation on Ubuntu 25.10 with GCC 15.2.0

[arkq]

Trying to compile generated tests on Ubuntu 25.10 results in a compilation error due to name clash between test case namespace and function from the standard library:

Pull request overview

This PR fixes a compilation error on Ubuntu 25.10 with GCC 15.2.0 caused by a namespace collision. The standard library now includes a rsqrt() function, which conflicts with test case namespaces named rsqrt. The fix adds a prefix to all generated test namespaces to avoid such collisions.

Changes:

• Modified test generators to add namespace prefixes: vts_gen_ for VTS tests and cts_gen_ for CTS tests
• Updated all namespace references in generated test templates to use the prefixed names
• Added Samsung copyright notice to modified shell script

File	Description
runtime/tests/nnapi/specs/generate_vts_test.sh	Updated shell script to generate namespaces with vts_gen_ prefix and reference them correctly
runtime/tests/nnapi/nnapi_test_generator/android-10/vts_generator.py	Modified VTS test generator to use vts_gen_ namespace prefix in generated code
runtime/tests/nnapi/nnapi_test_generator/android-10/cts_generator.py	Modified CTS test generator to use namespace prefix (contains critical typo: ctc_gen_ instead of cts_gen_)
