ENH: Add more conditions for attempting to call the new Visual Studio macros. Only try to call them if the vsmacros file exists and is registered. Count VS instances again after warning about running instances. If user closed them in response to the warning, it's OK to register the macros now rather than waiting till the next CMake generate.
