The CI container had torchao 0.14.0 which is incompatible with recent peft (requires >=0.16.0), causing test_salm_lora to fail. Upgrade the base NGC PyTorch image to 26.03 (torchao 0.17, PyTorch 2.11) and drop all build/install machinery for Apex, TransformerEngine, Megatron-LM, and TensorRT-LLM since NeMo is now Speech AI only.

Re-add trt-llm entry in manifest.json, trt()/trtllm() functions in
install_dep.sh, TRTLLM build args in CI workflows, trt_llm.patch, and
the external/patches bind mount in Dockerfile.ci.

The wheel package is debian-installed without a RECORD file in
pytorch:26.03-py3, causing 'pip install -U wheel' to fail with
'uninstall-no-record-file'. Install wheel separately with
--ignore-installed so pip places a newer version in the higher-priority
/usr/local site-packages directory.
