gh-61103: Support float and long double complex types in ctypes module (#121248)
This amends 6988ff02a5: memory allocation for
stginfo->ffi_type_pointer.elements in PyCSimpleType_init() should be
more generic (perhaps someday fmt->pffi_type->elements will be not a
two-elements array).

It should finally resolve #61103.

gh-61103: Support double complex (_Complex) type in ctypes (#120894)
Example:

```pycon
>>> import ctypes
>>> ctypes.__STDC_IEC_559_COMPLEX__
1
>>> libm = ctypes.CDLL('libm.so.6')
>>> libm.clog.argtypes = [ctypes.c_double_complex]
>>> libm.clog.restype = ctypes.c_double_complex
>>> libm.clog(1+1j)
(0.34657359027997264+0.7853981633974483j)
```
