headers: crt: forbid deprecated DLLs APIs in winstore builds

They are not allowed:
https://docs.microsoft.com/en-us/cpp/cppcx/crt-functions-not-supported-in-universal-windows-platform-apps?view=vs-2019

"These were obsolete functions in previous CRT versions. Also, user cannot load
DLLs except from those in the same application package."
