MNT: support python 3.10

In python/cpython#20290 CPython changed
`Py_TYPE` from a macro to an inline function.  This requires a code
change to us `Py_SET_TYPE` instead when using `Py_TYPE()` as a lvalue
in c code.

In python/cpython#20429 CPython changed
`Py_SIZE` from a macro to an inline function.  This requires a code
change to us `Py_SET_SIZE` instead of using `Py_SIZE` as a lvalue in c
code.
