[hipDNN] Add matmul frontend integration tests

[jovanau]

Motivation

This PR addresses hipDNN issue #4951, which requests adding missing frontend integration test coverage for the Matmul operation.

Technical Details

This PR includes three changes:

1. FrontendGraphFactory support for Matmu

Added MATMUL to OperationType.
Added switch‑case dispatch in FrontendGraphFactory::create().
Implemented createMatmulGraph() using:

graph.matmul(a, b, matmulAttrs);

with simple 2×3 and 3×4 matrix inputs for deterministic testing.

2. Added new integration test: IntegrationMatmul.cpp

Following the structure of IntegrationConvForward.cpp, the test:

• is parameterized with:
  • good plugin
  • execute‑fail plugin
  • no‑engines plugin
• tests both auto‑assigned and manual UIDs
• builds a small Matmul graph using float tensors
• exercises the entire frontend execution pipeline:

validate() → build_operation_graph() → create_execution_plans()
→ check_support() → build_plans() → get_workspace_size() → execute()

• uses SKIP_IF_NO_DEVICES() for GPU‑dependent execution
• creates variant packs using device memory from the test tensor bundle
• verifies expected failures for execute‑fail and no‑engines plugins

3. CMake update

Added IntegrationMatmul.cpp to tests/frontend/CMakeLists.txt under public_hipdnn_frontend_tests.

Test Plan

All tests were built and executed inside the official TheRock docker environment.

ty ty for the updates!

Kicking off CI.

[BrianHarrisonAMD]

I kicked off the CI once more.
Please let this one run fully without updating!

Each change I have to re-approve the CI run, and I think this is ready to go in once we get a green run.
ty ty.

Sorry about that.
All the tests passed yesterday, and I accidentally clicked to update the branch. I’m not sure why they’re failing now.

No worries!
Looks like machine issues. I re-kicked it.

Might be due to the github issues happening right now.
Ill try rekicking it again once things are resolved.
