VS: Add Visual Studio 16 2019 generator

Add this generator *without* support for specifying the target
architecture in the generator name.  cmake-gui will be taught
to provide a field for this, and command-line builds can use -A.

Also, teach this generator to select a default target architecture
based on the host architecture.

Fixes: #18689

+Visual Studio 16 2019
+---------------------
+
+Generates Visual Studio 16 (VS 2019) project files.
+
+Project Types
+^^^^^^^^^^^^^
+
+Only Visual C++ and C# projects may be generated.  Other types of
+projects (JavaScript, Powershell, Python, etc.) are not supported.
+
+Instance Selection
+^^^^^^^^^^^^^^^^^^
+
+VS 2019 supports multiple installations on the same machine.
+The :variable:`CMAKE_GENERATOR_INSTANCE` variable may be set as a
+cache entry containing the absolute path to a Visual Studio instance.
+If the value is not specified explicitly by the user or a toolchain file,
+CMake queries the Visual Studio Installer to locate VS instances, chooses
+one, and sets the variable as a cache entry to hold the value persistently.
+
+When CMake first chooses an instance, if the ``VS160COMNTOOLS`` environment
+variable is set and points to the ``Common7/Tools`` directory within
+one of the instances, that instance will be used.  Otherwise, if more
+than one instance is installed we do not define which one is chosen
+by default.
+
+Platform Selection
+^^^^^^^^^^^^^^^^^^
+
+The default target platform name (architecture) is that of the host.
+
+The :variable:`CMAKE_GENERATOR_PLATFORM` variable may be set, perhaps
+via the :manual:`cmake(1)` ``-A`` option, to specify a target platform
+name (architecture).  For example:
+
+* ``cmake -G "Visual Studio 16 2019" -A Win32``
+* ``cmake -G "Visual Studio 16 2019" -A x64``
+* ``cmake -G "Visual Studio 16 2019" -A ARM``
+* ``cmake -G "Visual Studio 16 2019" -A ARM64``
+
+Toolset Selection
+^^^^^^^^^^^^^^^^^
+
+The ``v142`` toolset that comes with Visual Studio 16 2019 is selected by
+default.  The :variable:`CMAKE_GENERATOR_TOOLSET` option may be set, perhaps
+via the :manual:`cmake(1)` ``-T`` option, to specify another toolset.

+vs2019
+------
+
+* The :generator:`Visual Studio 16 2019` generator was added.  This is
+  experimental and based on "Visual Studio 2019 Preview 1.1" because this
+  version of VS has not been released.
+
+  The VS 2019 generator differs from generators for earlier versions
+  in that it does not provide variants that specify the target platform
+  in the generator name.  Instead :variable:`CMAKE_GENERATOR_PLATFORM`
+  must be used, e.g. through the ``-A`` command-line option.  Furthermore,
+  the default target platform (architecture) is now based on the *host*
+  platform.
