[AMD][ROCM] Add MI355X config: glm5-fp4-mi355x-sglang-mtp

- Add `glm5-fp4-mi355x-sglang-mtp` config to amd-master.yaml.
- Add benchmarks/single_node/glm5_fp4_mi355x_mtp.sh launch script.
- Image: lmsysorg/sglang-rocm:v0.5.10.post1-rocm700-mi35x-20260428
- Model: amd/GLM-5-MXFP4 (TP=8, FP4/quark quantization)
- EAGLE MTP speculative decoding: num-steps=3, eagle-topk=1,
  num-draft-tokens=4, behind SGLANG_ENABLE_SPEC_V2=1
- Search space: 1k1k and 8k1k, conc 4-64, spec-decoding=mtp
- Append perf-changelog.yaml entry.
