I would suggest enabling the samples building in the build job by cmake option: ENABLE_SAMPLES in pipelines where we need to build all of them, for benchmark_app we can use build_samples.sh -i ${INSTALL_DIR} -b ${BUILD_DIR}/cpp_samples/benchmark_app.
At this approach we will not upload all the samples (just a benchmark_app)

Pull request overview

This PR updates OpenVINO’s GitHub Actions CI so that C++/C samples are built during the main Build reusable workflows and their binaries are included in the produced openvino_package artifacts, reducing duplicated work in downstream test jobs.

Changes:

• Add a build-samples workflow_call input to job_build_linux.yml and job_build_windows.yml, and build/install sample binaries into ${INSTALL_DIR}/samples_bin when enabled.
• Enable build-samples: true in key platform pipelines (Ubuntu 22/24, Linux arm64, Windows VS2022 Release, Level Zero GPU dev flow).
• Remove redundant sample build steps from job_samples_tests.yml and job_gpu_tests.yml (keeping only a Linux Clang rebuild check for C++ samples), and add a samples build step to mac_arm64.yml before packing artifacts.

.github/workflows/job_samples_tests.yml	Removes GCC sample rebuilds; keeps a Linux Clang rebuild check and relies on samples_bin from openvino_package.
.github/workflows/job_gpu_tests.yml	Stops rebuilding samples in GPU tests; relies on sample binaries provided by openvino_package.
.github/workflows/job_build_windows.yml	Adds build-samples input and conditionally builds/installs C++/C samples into the package.
.github/workflows/job_build_linux.yml	Adds build-samples input and conditionally builds/installs C++/C samples into the package.
.github/workflows/dev_gpu_linux_level_zero.yml	Enables build-samples so GPU tests can run sample executables from the packaged artifacts.

That can be a bit confusing. If we set build-samples: true, why do we need to set it explicitly in the CMake options as well?

[mryzhov]

maybe it would be better to use one of them only? build-samples: true for example, and set cmake option in the build job

[akashchi]

Remove the cmake option, now solely controlled by build-samples.
