Peter Eisentraut 2bc60f8621 Enable Python Limited API for PL/Python on MSVC
Previously, the Python Limited API was disabled on MSVC due to build
failures caused by Meson not knowing to link against python3.lib
instead of python3XX.lib when using the Limited API.

This commit works around the Meson limitation by explicitly finding
and linking against python3.lib on MSVC, and removes the preprocessor
guard that was disabling the Limited API on MSVC in plpython.h.

This requires python3.lib to be present in the Python installation,
which is included when Python is installed.
