Gregor Jasny b78a14e204 Xcode: reject legacy buildsystem for Xcode 14
With Xcode 14 support for the Legacy Build System has been removed
and the BuildSystemType in the WorkspaceSettings is ignored.
If CMake still generates projects targeted to the Lecacy Build
System the build preparation phase will likely fail because Xcode
for example misses any declared outputs from script invocations.

This is a hard to debug problem and CMake should reject the invalid
configuration instead.

CMAKE_XCODE_BUILD_SYSTEM
------------------------
.. versionadded:: 3.19
Xcode build system selection.
The :generator:`Xcode` generator defines this variable to indicate which
variant of the Xcode build system will be used. The value is the
version of Xcode in which the corresponding build system first became
mature enough for use by CMake. The possible values are:
``1``
The original Xcode build system.
This is the default when using Xcode 11.x or below and supported
up to Xcode 13.x.
``12``
The Xcode "new build system" introduced by Xcode 10.
It became mature enough for use by CMake in Xcode 12.
This is the default when using Xcode 12.x or above.
The ``CMAKE_XCODE_BUILD_SYSTEM`` variable is informational and should not
be modified by project code. See the :ref:`Xcode Build System Selection`
documentation section to select the Xcode build system.
