Re-enable removed Windows builds 12 months ago

AI Summary: This issue aims to re-enable several Windows CI builds (specifically Clang, Clang-CL, and certain MSVC versions) that were previously disabled. The removal was a temporary fix due to the deprecation of the `windows-2019` runner image, and the goal is to restore these builds by migrating them to a newer Windows environment where feasible.

LIBCPP_VERSION_OUTPUT breaks cross-compilation and is not used anywhere about 1 year ago

AI Summary: The task is to investigate why the LIBCPP_VERSION_OUTPUT variable in the nlohmann/json project causes CMake configuration failures during cross-compilation, especially for RISC-V architecture. The variable appears unused, and the goal is to determine its impact and either remove it or fix its usage to resolve the cross-compilation issue.
