In the same places that FIND_LIBRARY_USE_LIB32_PATHS documentation was
added.  Add a `Help/prop_gbl/FIND_LIBRARY_USE_CUSTOM_SUFFIX.rst` and
associated links to it.

Actually I was asking in what source code context the actual

 set(LIB_SUFFIX ...)
 set_property(GLOBAL PROPERTY FIND_LIBRARY_USE_CUSTOM_SUFFIX ...)

lines would appear.  CMake sets the lib32/lib64 ones in its own
platform modules for the relevant platforms so user code never
needs to do it.  Where in user code would it be done?
