Help: Revise buildsystem artifact file type documentation (#15539)

Add sections to the cmake-buildsystem(7) manual and cross-reference
them with relevant variables and target properties.  This avoids
duplicating the information and allows it to be more detailed.

+There are three kinds of output artifacts that may be build by targets
+as detailed in the following sections.  Their classification differs
+between DLL platforms and non-DLL platforms.  All Windows-based
+systems including Cygwin are DLL platforms.
+
+.. _`Runtime Output Artifacts`:
+
+Runtime Output Artifacts
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+A *runtime* output artifact of a buildsystem target may be:
+
+* The executable file (e.g. ``.exe``) of an executable target
+  created by the :command:`add_executable` command.
+
+* On DLL platforms: the executable file (e.g. ``.dll``) of a shared
+  library target created by the :command:`add_library` command
+  with the ``SHARED`` option.
+
+The :prop_tgt:`RUNTIME_OUTPUT_DIRECTORY` and :prop_tgt:`RUNTIME_OUTPUT_NAME`
+target properties may be used to control runtime output artifact locations
+and names in the build tree.
+
+.. _`Library Output Artifacts`:
+
+Library Output Artifacts
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+A *library* output artifact of a buildsystem target may be:
+
+* The loadable module file (e.g. ``.dll`` or ``.so``) of a module
+  library target created by the :command:`add_library` command
+  with the ``MODULE`` option.
+
+* On non-DLL platforms: the shared library file (e.g. ``.so`` or ``.dylib``)
+  of a shared shared library target created by the :command:`add_library`
+  command with the ``SHARED`` option.
+
+The :prop_tgt:`LIBRARY_OUTPUT_DIRECTORY` and :prop_tgt:`LIBRARY_OUTPUT_NAME`
+target properties may be used to control library output artifact locations
+and names in the build tree.
+
+.. _`Archive Output Artifacts`:
+
+Archive Output Artifacts
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+An *archive* output artifact of a buildsystem target may be:
+
+* The static library file (e.g. ``.lib`` or ``.a``) of a static
+  library target created by the :command:`add_library` command
+  with the ``STATIC`` option.
+
+* On DLL platforms: the import library file (e.g. ``.lib``) of a shared
+  library target created by the :command:`add_library` command
+  with the ``SHARED`` option.
+
+* On DLL platforms: the import library file (e.g. ``.lib``) of an
+  executable target created by the :command:`add_executable` command
+  when its :prop_tgt:`ENABLE_EXPORTS` target property is set.
+
+The :prop_tgt:`ARCHIVE_OUTPUT_DIRECTORY` and :prop_tgt:`ARCHIVE_OUTPUT_NAME`
+target properties may be used to control archive output artifact locations
+and names in the build tree.
