Enable building of NVBench on Windows

[oleksandr-pavlyk]

No testing on Windows is intended.

This PR wants to add CI plumbing to enable testing of #354, but the Windows build in this PR is expected to fail.

The plan is

• test github action and script
• verify that failure is due to compilation failure
• disable the windows build and merge

Then in #354, the main would be merged, windows build job enabled to permit iterations.

Walkthrough

This PR adds complete Windows build infrastructure to NVBench's CI system. It defines an MSVC2022 compiler configuration in the matrix, creates a reusable build-windows.yml workflow with Docker container execution, introduces a PowerShell build module with CMake orchestration functions, and adds a Windows-specific build script integrated into the PR workflow.

Changes

Windows CI Build Support

Layer / File(s)	Summary
Matrix configuration and export ci/matrix.yaml, .github/actions/compute-matrix/compute-matrix.sh, .github/workflows/pr.yml	CI matrix adds msvc2022 compiler anchor and Windows build variant (cuda_curr_max, MSVC, amd64, C++17); compute-matrix script extracts and transforms Windows configurations; pr.yml exports WINDOWS_MATRIX output.
Reusable Windows build workflow definition .github/workflows/build-windows.yml	New workflow exposes workflow_call and workflow_dispatch interfaces parameterized by CUDA version, host compiler tag, devcontainer version, image, runner, C++ standard (17/20), and optional CUDA architecture; sets read-only repository permissions.
Windows build job setup .github/workflows/build-windows.yml	Job configures dynamic runner selection, establishes SCCACHE environment variables, checks out repository, registers NVCC problem matcher, conditionally assumes AWS OIDC role for cache access (NVIDIA/nvbench only), and pulls devcontainer image.
Windows build execution step .github/workflows/build-windows.yml	Main build step generates temporary PowerShell script, constructs docker run with workspace bind-mount to C:/nvbench, forwards CI/AWS/SCCache/GitHub environment variables, executes container's build_nvbench.ps1 with standard and architecture parameters, and propagates exit codes.
PowerShell build orchestration module ci/windows/build_common.psm1	Module provides parameter validation, fail-fast error handling, CMake option parsing, compiler/toolchain setup, and exported functions: Print-EnvironmentDetails, Configure-Preset, Build-Preset, Configure-And-Build-Preset; helper functions support sccache integration and native command invocation.
NVBench Windows build script ci/windows/build_nvbench.ps1	Entry point script validates C++ standard (17/20), accepts optional CUDA architecture and CMake options; manages working directory state via try/finally; imports build_common and invokes Configure-And-Build-Preset for nvbench-ci preset with CMAKE_CXX_STANDARD and CMAKE_CUDA_STANDARD.
PR workflow integration .github/workflows/pr.yml	New nvbench-windows job runs build-windows.yml with matrix from WINDOWS_MATRIX, forwarding build parameters; ci job dependency list includes nvbench-windows for gating final status checks.

Poem

🐰 A Windows build path now appears,
With matrices and workflows clear,
PowerShell scripts orchestrate the dance,
Docker containers join the prance,
NVBench builds on Windows with flair! ✨

In @.github/workflows/pr.yml:
- Around line 80-99: The nvbench-windows job is currently blocking merges while
failures are expected; make it non-blocking by adding continue-on-error: true to
the nvbench-windows job definition (the job named "nvbench-windows") and also
remove nvbench-windows from the dependency/needs list of the final "ci" job (or
otherwise avoid marking it as a required check) so the ci job does not treat
nvbench-windows as a blocking prerequisite. Ensure you edit the nvbench-windows
job block to include continue-on-error: true and update the "ci" job's needs so
it no longer depends on nvbench-windows.

Verified that job failed due to CMake failure, not due to issue with CI scripts:

CMake Error in CMakeLists.txt:
  IMPORTED_IMPLIB not set for imported target "nvbench::cupti" configuration
  "Release".
