Add GPU Support for GLiNERRecognizer and Validator Module for PII Detection

[thisaltennakoon]

This pull request introduces GPU support for the GLiNERRecognizer class and updates the validator module to allow GPU usage for PII detection. The changes include adding a use_gpu parameter, determining the device for model inference, and ensuring the model is loaded and executed on the appropriate device.

GPU Support for GLiNERRecognizer:

• Added a use_gpu parameter to the GLiNERRecognizer constructor to enable or disable GPU usage. The _get_device method determines whether to use a GPU or CPU based on availability and the use_gpu flag. (validator/gliner_recognizer.py, [1] [2]
• Updated the load method to move the model to the appropriate device and set it to evaluation mode if GPU is used. (validator/gliner_recognizer.py, validator/gliner_recognizer.pyR24-R44)
• Modified the analyze method to ensure the model is on the correct device and to disable gradients during inference for efficiency. (validator/gliner_recognizer.py, validator/gliner_recognizer.pyR24-R44)

Integration with validator Module:

• Added a use_gpu parameter to the Validator class constructor and passed it to the GLiNERRecognizer instance when use_local is enabled. (validator/main.py, [1] [2] [3]
