Also write for all configurations from multi-config generators.

This field was added in the Clang 5 documentation and not present in the
Clang 4 documentation (sometime between Dec 2016 and Mar 2017 according
to `web.archive.org`).

compile-commands-output-field
-----------------------------
* The :prop_tgt:`EXPORT_COMPILE_COMMANDS` target property will now have the
``output`` field in the compile commands objects. This allows multi-config
generators (namely :generator:`Ninja Multi-Config` generator) to contain the
compile commands for all configurations.
