llama : Add FP8 KV-cache support (#28392)

• Add FP8 KV-cache support

• Add tests for scaled, FP8 KV-cache to test-backend-ops

• Fix get_*_scale mapping and dequnatize FP8 also before rope shift

• Normalizes cache-scale names independently of projection layout.

While fused KQV is currently impractival for non-shared scales, this is
an improvement for future use regardless

• Enable Gemma 4 Assistant with FP8 by storing and fetching scale ptrs

• Update comment wording

• Move E2E FP8 KV cache tests to test-llama-archs

They belong there as they are not just a test for ggml's backend ops

• Increase support surface, remove seed

• make scaled kv generic

• Fix CI failings for test-kv-cache

https://github.com/ggml-org/llama.cpp/actions/runs/38718763447/job/116367842578?pr=28392

• CI: execute kv-cache-scale tests

• exclude fp8-kv tests from OpenVINO

• Fix linting errors of test_kv_cache_scales

• Disable kv-ffload=false + multi-GPU tests for FP8

See https://github.com/ggml-org/llama.cpp/actions/runs/38952722084/job/117148353699?pr=28413

• Adjust test label for test-kv-cache.cpp

• Fix conflict-resolution mistakes in test-kv-cache.cpp

https://github.com/ggml-org/llama.cpp/actions/runs/40554674463/job/122367426461?pr=28392

• Fix fp8 kv cache test by population kv_source_impl

• Exclude models that consume KV cache directly

• Remove obsolete comment

• Allow BF16 scales as well for KV cache

• Rename *_cache_scale to *_cache_s
