Teach GenerateBuildCommand to find its own make program

Add a cmGlobalGenerator::SelectMakeProgram method to select a
caller-provided make program, the CMAKE_MAKE_PROGRAM cache entry, or a
generator-provided default.  Call it from all implementations of the
GenerateBuildCommand method with the corresponding generator's default,
if any.
