Pull Request Overview

This PR pins the MSVC toolchain version and adds an automatic minimum version check for msvcp140.dll to help ensure process stability. Key changes include:

• Updating job scripts (jenkins_win.ps1 and build_server_win.ps1) to use a fixed MSVC toolchain version.
• Modifying the build configuration in CMakeLists.txt and platform_win.cmake to improve parallel build settings.
• Introducing a new DLL (MSVC/dllmain.c) that performs a runtime version check on msvcp140.dll.

The order of version numbers is inconsistent with the defined version structure; the 'build' value should be printed before the 'revision' to correctly reflect the version as major.minor.build.revision.
