meson: ensure -mcx16 is passed when detecting ATOMIC128
Moving -mcx16 out of CPU_CFLAGS caused the detection of ATOMIC128 to
fail, because flags have to be specified by hand in cc.compiles and
cc.links invocations (why oh why??).
Ensure that these tests enable all the instruction set extensions that
will be used to build the emulators.
Fixes: c2bf2ccb266 ("configure: move -mcx16 flag out of CPU_CFLAGS", 2024-05-24)
