Clean up complex.h handling of float128.
This patch cleans up the way complex.h handles inclusion of
bits/cmathcalls.h for float128. The inclusion was between those for
the types float and long double; the patch moves it after that for
long double, matching how bits/mathcalls.h and bits/math-finite.h
inclusions are ordered. There is no need for the undefine and define
of _Mdouble_complex_ to be conditional, since __CFLOAT128 is always
defined by bits/floatn.h when _Float128 is supported, so the patch
removes the unnecessary conditionals.
Tested for x86_64.
* math/complex.h
[(__HAVE_DISTINCT_FLOAT128 || (__HAVE_FLOAT128 && !LIBC))
&& __GLIBC_USE (IEC_60559_TYPES_EXT)]: Move conditional code after
that for long double. Do not condition define and undefine of
_Mdouble_complex_ on [__CFLOAT128].
