ExternalProject: Added new USES_TERMINAL options
Added new USES_TERMINAL option to the ExternalProject_Add_Step function. This option passes USES_TERMINAL to the underlying add_custom_command call so that the Ninja console pool is used. Also, corresponding new USES_TERMINAL_<step> options were added to the ExternalProject_Add function. Justification: if using Ninja with a CMake superbuild, it's often desirable to limit the superbuild to ONE sub-Ninja process at a time to avoid oversubscribing the CPU. Using the console pool also makes it easy to monitor the progress of the sub-Ninja process. Independent USES_TERMINAL_<step> arguments are passed to ExternalProject_Add instead of one USES_TERMINAL argument that controls everything. Users may wish to run some steps in parallel but not others (e.g. parallelize configure but not build).
