Move QEMU_ALIGN_*() from qemu-common.h to qemu/osdep.h

qemu-common.h should only be included by .c files.  Its file comment
explains why: "No header file should depend on qemu-common.h, as this
would easily lead to circular header dependencies."

One of the reasons for headers to include it is QEMU_ALIGN_UP() and
QEMU_ALIGN_DOWN().  Move them next to ROUND_UP() in qemu/osdep.h, to
facilitate removing these ill-advised includes later on.
