[wgzintel]

When setting OPENVINO_LOG_LEVEL, print the info of scheduler_config.

SchedulerConfig {
max_num_batched_tokens: 18446744073709551615
num_kv_blocks: 0
cache_size: 0
dynamic_split_fuse: 1
use_cache_eviction: 0
max_num_seqs: 256
enable_prefix_caching: 0
use_sparse_attention: 0
}

Pull Request Overview

This PR adds debug logging capability for scheduler configuration information when the OPENVINO_LOG_LEVEL environment variable is set. It implements to_string() methods for various configuration classes and integrates scheduler config printing into the ContinuousBatchingPipeline constructors.

Key changes:

• Added to_string() methods to SchedulerConfig, SparseAttentionConfig, CacheEvictionConfig, and KVCrushConfig classes
• Added utility function print_scheduler_config_info() to conditionally print scheduler configuration
• Integrated scheduler config printing into all ContinuousBatchingPipeline constructor paths
