Teach find_library and find_package to search lib32 paths (#11260)
Add a ``FIND_LIBRARY_USE_LIB32_PATHS`` global property analogous to the ``FIND_LIBRARY_USE_LIB64_PATHS`` property. This helps find commands on multilib systems that use ``lib32`` directories and either do not have ``lib`` symlinks or point ``lib`` to ``lib64``.

+Whether the :command:`find_library` command should automatically search

+
+``FIND_LIBRARY_USE_LIB32_PATHS`` is a boolean specifying whether the
+:command:`find_library` command should automatically search the ``lib32``
+variant of directories called ``lib`` in the search path when building 32-bit
+binaries.
