The value of `CMAKE_VS_PLATFORM_NAME` is computed by Visual Studio generators based on `CMAKE_GENERATOR_PLATFORM` or some default. Prior to the VS 2019 generator, the default was always `Win32`. However, for the `Visual Studio 16 2019` generator, the default is based on the host platform. Store the default in a new `CMAKE_VS_PLATFORM_NAME_DEFAULT` variable for use by project code. This is particularly useful in toolchain files because they are allowed to set `CMAKE_GENERATOR_PLATFORM` and so `CMAKE_VS_PLATFORM_NAME` is not yet known. Of course the toolchain file author knows whether it will set `CMAKE_GENERATOR_PLATFORM`, and if not then `CMAKE_VS_PLATFORM_NAME_DEFAULT` provides the platform name that will be used. Fixes: #19177

variable. For :ref:`Visual Studio Generators` for VS 2017 and below this is

always ``Win32``. For VS 2019 and above this is based on the host platform.
