This is a simple move of all header files that are no longer included by anything else from the include/mach directory to the platform directory itself as preparation for multiplatform support. The mach/uncompress.h headers are left in place for now, and are mildly modified to be independent of the other headers. They will be removed entirely when ARCH_MULTIPLATFORM gets enabled and they become obsolete. Rather than updating the path names inside of the comments of each header, I delete those comments to avoid having to update them again, should they get moved or copied another time.
