Add patch to resolve GStreamer pipeline failures when using TensorFlow Lite object detection models. The tensorflow2-lite NNStreamer plugin was failing to load due to missing Abseil logging symbols (_ZN4absl12lts_2025012712 log_internal9kCharNullE, _ZN4absl12lts_2025012712log_internal10LogMessage C1EPKciNS2_8ErrorTagE) in the libtensorflow-lite.so.2 shared library.
The fix adds missing Abseil logging targets to the CMake build system and links required logging libraries (log_internal_nullguard, log_internal_message, log_severity, raw_logging_internal) to ensure all symbols are available at runtime.
