Introducing automatic LLM optimization with TensorRT-LLM Engine Builder

Introduces the TensorRT-LLM Engine Builder, which automates the creation of optimized LLM inference engines at deploy time. This addresses challenges of long setup times, hardware compatibility issues for engine building, and manual packaging/deployment. The builder integrates with Truss for model packaging and Baseten's platform for autoscaling, logging, and security. It leverages TensorRT-LLM's capabilities for model specialization, quantization, in-flight batching, and LoRA swapping to achieve low-latency, high-throughput inference.
