Issue Description:

Although /MD and /MDd cannot be mixed, it should be possible to build both debug and release variants and provide the runtime as `swiftCore.dll` and `swiftCored.dll` and be able to build both /MD and /MDd to enable debug builds.

Contributor guide

Research direction
Examine the CMake build scripts in the Swift repository for Windows to understand how swiftrt.obj and swiftCore are currently built. Look for conditions that enforce /MD or /MDd and propose changes to build both variants.
