This replaces swiftMSVCRT with swiftCRT. The big difference here is that the `visualc` module is no longer imported nor exported. The `visualc` module remains in use for a singular test wrt availability, but this should effectively remove the need for the `visualc` module. The difference between the MSVCRT and ucrt module was not well understood by most. MSVCRT provided ucrt AND visualc, combining pieces of the old MSVCRT and the newer ucrt. The ucrt module is what you really wanted most of the time, however, would need to use MSVCRT for the convenience aliases for type-generic math and the deprecated math constants. Unfortunately, we cannot shadow the `ucrt` module and create a Swift SDK overlay for ucrt as that seems to result in circular dependencies when processing the `_Concurrency` module. Although this makes using the C library easier for most people, it has a more important subtle change: it cleaves the dependency on visualc. This means that this enables use of Swift without Visual Studio for the singular purpose of providing 3 header files. Additionally, it removes the need for the installation of 2 of the 4 support files. This greatly simplifies the deployment process on Windows.
