Add perf workflow

[lukaszstolarczuk]

Add initial workflow for performance measurements.

// Preview run for main branch: https://github.com/oneapi-src/unified-memory-framework/actions/runs/10996891676/job/30531119551
// manual workflow can be tested only if this workflow is merged.

How are the measurements meant to be viewed when benchmarks are ran on main and the comment is skipped?
The Run benchmarks section from your preview looks like this:

Run numactl -N 1 ctest -V --test-dir benchmark -C Release
Internal ctest changing into directory: /home/test-user/shared-actions-runner/_work/unified-memory-framework/unified-memory-framework/benchmark
UpdateCTestConfiguration  from :/home/test-user/shared-actions-runner/_work/unified-memory-framework/unified-memory-framework/benchmark/DartConfiguration.tcl

thx @kswiecicki - fixed the bug with no tests (I was in the wrong directory).

As for results from benchmarks run on main - as we can see in UR, this scenario is rarely run - we rather want results for specific PR; and of course, there are logs in the CI.

When we have a final version of benchmarks we can tweak this workflow to print some more results; for now we only run basic benchmark just to check if the workflow is running properly.
