docs: update TensorRT-LLM commit for multimodal EPD to v1.2.0rc3

Summary

Updates the TensorRT-LLM commit reference from v1.2.0rc2 to v1.2.0rc3 in the multimodal EPD documentation.

Changes

• Updated docs/backends/trtllm/multimodal_epd.md to use --tensorrtllm-commit v1.2.0rc3

Motivation

The EPD (Encode-Prefill-Decode) feature requires a specific TensorRT-LLM version. This update pins to the latest release candidate v1.2.0rc3 to ensure users build with the correct tested version.

Timestamp: 2025-08-30T20:43:10.091Z
Learning: In the dynamo project, devcontainer.json files use templated container names (like "dynamo-vllm-devcontainer") that are automatically processed by the copy_devcontainer.sh script to generate framework-specific configurations with unique names, preventing container name collisions.

Timestamp: 2025-12-02T18:13:40.037Z
Learning: In the ai-dynamo/dynamo repository, backend-specific tests (vllm, sglang, trtllm) are intentionally excluded from the container-validation-dynamo.yml workflow using "not (vllm or sglang or trtllm)" because they run in a separate container-validation-backends.yml workflow that has dedicated jobs for each backend. This separation keeps framework-agnostic tests separate from backend-specific tests.

Learning: The `--torch-backend=auto` flag works with vLLM installations via uv pip install, even though it's not a standard pip option. This flag is processed by vLLM's build system during installation to automatically match PyTorch distribution with container CUDA versions.

10-12: Version reference updated correctly.

The TensorRT-LLM commit has been properly bumped from v1.2.0rc2 to v1.2.0rc3 in the build instruction. This aligns with the PR objective to pin documentation to the tested release candidate version for the EPD feature.
