Cherry-pick of #4358 onto release/2.13.

Conflict resolved in core/runtime/BUILD:

  • MD-TRT changes for release 2.13 #4358 (authored on main) converted NCCL from copts = if_torch_nccl(["-DUSE_C10D_NCCL"]) to defines = if_torch_nccl(["USE_C10D_NCCL"]) + select({... TRT_HAS_IRUNTIME_CONFIG ...}).
  • The select({... TRT_HAS_IRUNTIME_CONFIG ...}) block and its RuntimeSettings.h / TRTRuntimeConfig.h headers are pre-existing main infrastructure that does not exist on release/2.13.
  • Resolution: kept release/2.13's existing copts = if_torch_nccl(["-DUSE_C10D_NCCL"]) and dropped the IRuntimeConfig block. The two Python changes (_utils.py, _TRTInterpreter.py) applied cleanly.

Original PR: #4358
