Move platform specific Linux headers under include/os/linux/. Update the build system accordingly to detect the platform. This lays some of the initial groundwork to supporting building for other platforms. As part of this change it was necessary to create both a user and kernel space sys/simd.h header which can be included in either context. No functional change, the source has been refactored and the relevant #include's updated.
