Add ROCm 7.0 support

[arsdragonfly]

Description

Adds a ROCm 7.0 dockerfile and the cross-cutting changes that first become
relevant at this version.

Depends on #812. While #812 is unmerged, this PR's diff also includes
the ROCm 6.4 changes; once #812 merges into main, the diff here will
shrink to just the 7.0-specific commit.

This PR is the second of three stacked PRs that split #810 by ROCm version:

1. Add ROCm 6.4 support #812 — Add ROCm 6.4 support
2. This PR — Add ROCm 7.0 support
3. Add ROCm 7.2 support (stacked on this one)

Changes (7.0-specific)

• dockerfile/rocm7.0.x.dockerfile — new ROCm 7.0 image.
• third_party/Makefile — inject <cassert> into hipBusBandwidth.cpp;
  newer clang in ROCm ≥ 7 rejects assert() without it.
• superbench/benchmarks/micro_benchmarks/hipblaslt_function.py — parse
  hipblaslt-bench output by header-name lookup, so the parser handles
  both the legacy 23-column schema and the new 33+ column schema (extra
  type/scale/GB-s columns) introduced in hipBLASLt 7.x.
• tests/benchmarks/micro_benchmarks/test_hipblaslt_function.py —
  regression test for the new schema.
• .github/workflows/build-image.yml — add rocm7.0 matrix entry.

Pull request overview

This PR adds ROCm 7.0 support to SuperBench’s container/tooling stack and updates a couple of micro-benchmarks to stay compatible with ROCm 7.x toolchain/output changes.

Changes:

• Add new ROCm 6.4 and ROCm 7.0 Docker images and wire them into the image build workflow matrix.
• Make hipblaslt-bench result parsing schema-robust by resolving columns via the header row (supports both older ~23-col and newer 33+ col outputs), plus a regression test.
• Update ROCm-related native build bits (HIP bandwidth sample <cassert> include injection; GPU stream benchmark ROCm support via rocm_smi).
