qemu/atomic: Rename atomic128-cas.h headers using .h.inc suffix

Since commit 139c1837db ("meson: rename included C source files
to .c.inc"), QEMU standard procedure for included C files is to
use *.c.inc.

Besides, since commit 6a0057aa22 ("docs/devel: make a statement
about includes") this is documented in the Coding Style:

  If you do use template header files they should be named with
  the ``.c.inc`` or ``.h.inc`` suffix to make it clear they are
  being included for expansion.

Therefore rename 'atomic128-cas.h' as 'atomic128-cas.h.inc'.
