Ninja Multi-Config: Shuffle variables around

Remove redundant variable CMAKE_NINJA_MULTI_CROSS_CONFIG_ENABLE.
Rename other variables. Document and improve handling of error
conditions.

 instead of only one configuration with :variable:`CMAKE_BUILD_TYPE`. One
 ``build-<Config>.ninja`` file will be generated for each of these
 configurations (with ``<Config>`` being the configuration name.) No
-``build.ninja`` file is generated, unless
-:variable:`CMAKE_NINJA_MULTI_DEFAULT_BUILD_TYPE` is specified. You must specify

-``cmake --build . --config <Config> --target <target>`` will run Ninja with
-``build-<Config>.ninja`` as the ``-f`` file and ``<target>`` as the build
-target.
+``build.ninja`` file is generated by default (see below for how to generate
+it.)
 
-If :variable:`CMAKE_NINJA_MULTI_CROSS_CONFIG_ENABLE` is turned on, executables
-and libraries of any configuration can be built regardless of which
-``build-<Config>.ninja`` file is used, simply by specifying
-``<target>:<OtherConfig>`` as the Ninja target. You can also specify
-``<target>:all`` to build a target in all configurations. Each
-``build-<Config>.ninja`` file will additionally have ``<target>`` targets which
-are aliases for ``<target>:<Config>``. However, custom commands and custom
-targets will always use the configuration specified in
-``build-<Config>.ninja``. This is due to the fact that it is impossible in
-Ninja for the same file to be output with different commands in the same build
-graph.
+Each ``build-<Config>.ninja`` file contains ``<target>`` targets as well as
+``<target>:<Config>`` targets, where ``<Config>`` is the same as the
+configuration specified in ``build-<Config>.ninja`` Additionally, if
+cross-config mode is enabled, ``build-<Config>.ninja`` may contain
+``<target>:<OtherConfig>`` targets, where ``<OtherConfig>`` is a cross-config,
+as well as ``<target>:all``, which builds the target in all cross-configs. See
+below for how to enable cross-config mode.
 
-You can additionally use :variable:`CMAKE_NINJA_MULTI_CROSS_CONFIGS` to limit
-the configurations that get cross-generated. If this variable is set, each
-``build-<Config>.ninja`` file will only contain rules for the configurations

-If :variable:`CMAKE_NINJA_MULTI_CROSS_CONFIG_ENABLE` is not enabled, you can

-``<target>:<Config>`` or ``<target>``, but not ``<target>:<OtherConfig>`` or
-``<target>:all``.
+:variable:`CMAKE_CONFIGURATION_TYPES`
+  Specifies the total set of configurations to build. See the variable's
+  documentation for more information.
+
+:variable:`CMAKE_NMC_CROSS_CONFIGS`
+  Specifies a :ref:`semicolon-separated list <CMake Language Lists>` of
+  configurations available from all ``build-<Config>.ninja`` files.
+  This variable activates cross-config mode.
+  Targets from each config specified in this variable can be built from any
+  ``build-<Config>.ninja`` file. Custom commands will use the configuration
+  native to ``build-<Config>.ninja``. If it is set to ``all``, all
+  configurations from :variable:`CMAKE_CONFIGURATION_TYPES` are cross-configs.

+
+:variable:`CMAKE_NMC_DEFAULT_BUILD_FILE_CONFIG`
+  Specifies the configuration to use by default in a ``build.ninja`` file. If
+  this variable is specified, a ``build.ninja`` file is generated which uses
+  build rules from ``build-<Config>.ninja`` by default. All custom commands are
+  executed with this configuration. If the variable is not specified, no
+  ``build.ninja`` file is generated.
+
+  The value of this variable must be one of the items from
+  :variable:`CMAKE_CONFIGURATION_TYPES`.
+
+:variable:`CMAKE_NMC_DEFAULT_CONFIGS`
+  Specifies a :ref:`semicolon-separated list <CMake Language Lists>` of
+  configurations to build for a target in ``build.ninja``
+  if no ``:<Config>`` suffix is specified. If it is set to ``all``, all
+  configurations from :variable:`CMAKE_NMC_CROSS_CONFIGS` are used. If
+  it is not specified, it defaults to
+  :variable:`CMAKE_NMC_DEFAULT_BUILD_FILE_CONFIG`.
+
+  For example, if you set
+  :variable:`CMAKE_NMC_DEFAULT_BUILD_FILE_CONFIG` to ``Release``, but
