Added option to enable CMake Install (swiftlang#2907)

Since SwiftPM does its own installation using the bootstrap script, it
hides the CMake install target to only be enabled on Windows which
doesn't use the bootstrap script. But when bootstrapping using CMake on
non Windows platforms, it would be nice to be able to enable them.
