Enable PGO for Windows builds (x64 and Arm64)

### What is the problem this feature will solve? Profile Guided Optimization has been available for some time now, and stats from projects that adopt PGO commonly show runtime perf improvements of around 10%. LLVM and MSVC offer PGO when building Windows apps for x64 and Arm64 ABI apps. This request is to investigate and implement PGO in the CI release jobs when building Windows versions of nodeJS for both Arm64 and x64 ABIs.

Add to the CI release jobs: - Enable PGO instrumentation profiling during first pass build. - execute nodejs using a predefined test script for most common scenarios to generate profile data - Relink the app using the profile data for optimization guidance. ### What alternatives have you considered? nonw
