Support more integer types in PyMemberDef

I plan to add more wrappers for Posix structures. Many of them use types not supported in PyMemberDef, like uint32_t or pid_t. So the first step is to add support of many standard C and Posix integer types.

gh-114388 and gh-115011 were preparations to this step.

The open question: should we assign new codes for new types or define them as aliases to existing types if they are already exist (for example, Py_T_PID can be an alias of Py_T_INT, Py_T_LONG or Py_T_LONGLONG, depending on platform).

まず gh-114388 と gh-115011 の準備を確認し、次に gh-117032 と gh-132550 の作業を調査します。新しい PyMemberDef 型コードやプラットフォーム依存のエイリアスが適切かどうかを解決し、issue に記載されている標準 C および POSIX の整数型のサポートを定義します。
