Always place try_compile executables predictably (#11724) 

Set CMAKE_RUNTIME_OUTPUT_DIRECTORY explicitly in try_compile projects so
that the COPY_FILE feature knows where to look.  This makes the feature
robust against CMAKE_USER_MAKE_RULES_OVERRIDE files that set variables
like CMAKE_RUNTIME_OUTPUT_DIRECTORY or EXECUTABLE_OUTPUT_PATH.
