[Win] Implement NetworkCacheBlobStorage.cpp without stat and unlink unlink is deprecated https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/unlink?view=vs-2019 _unlink https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/unlink-wunlink?view=vs-2019 _stat、_stat32、_stat64、_stati64、_stat32i64、_stat64i32、_wstat、_wstat32、_wstat64、_wstati64、_wstat32i64、_wstat64i32 | Microsoft Docs https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/stat-functions?view=vs-2019
Proper direction would be to convert as much as possible of NetworkCache code to be cross-platform by using our FileSystem abstractions, e.g. FileSystem::deleteFile instead of unlink In future we may want to use std::filesystem to implement some of operations
And where are substantial differences which require code to be #ifdef'ed, it would be better to avoid increasing of #ifdef's and instead separate parts of code to respective *POSIX.cpp and *Win.cpp files
