Once https://github.com/dotnet/corefx/issues/40740 is completed, the new API should be applied to the following APIs: [Interop.GetCurrentProcessId](https://github.com/dotnet/coreclr/blob/master/src/System.Private.CoreLib/shared/Interop/Windows/Kernel32/Interop.GetCurrentProcessId.cs) [Interop.GetCurrentThreadId](https://github.com/dotnet/coreclr/blob/master/src/System.Private.CoreLib/shared/Interop/Windows/Kernel32/Interop.GetCurrentThreadId.cs) [Interop.GetStdHandle](https://github.com/dotnet/coreclr/blob/master/src/System.Private.CoreLib/shared/Interop/Windows/Kernel32/Interop.GetStdHandle.cs) [Interop.SetThreadErrorMode](https://github.com/dotnet/coreclr/blob/master/src/System.Private.CoreLib/shared/Interop/Windows/Kernel32/Interop.SetThreadErrorMode.cs) All instances of the previous attribute name should be updated as well - see https://github.com/dotnet/coreclr/pull/26458.
