fix(strixhalo): add vllm runtime deps to --no-deps build

vllm was installed with --no-deps to avoid torch/xgrammar pin conflicts.
This left msgspec, fastapi, openai, xgrammar, and other runtime deps
missing. Now explicitly installs all vllm runtime deps in a separate
layer, with xgrammar in the --no-deps ROCm layer.
