Subject: [PATCH 1/2] Refactor numpy typecode generation in `_npsupport.py`.

Rename from `_check_ctypeslib_typecodes` to `_build_typecodes` for
clarity.

Subject: [PATCH 2/2] Refactor numpy typecode generation in `_npsupport.py`.

Remove overwriting `ctypeslib._typecodes` because `_typecodes` was
removed in `numpy==1.16` (`numpy` supporting Python3.8 is `1.17`
and above).
