Subject: [PATCH 01/11] Load the release CPython in Windows Debug builds

Debug Windows builds (flutter test, flutter run) bundled a debug build of
CPython (python3XY_d.dll, loaded through dart_bridge_d.dll). A debug CPython
only imports extension modules named *_d.pyd, which PyPI wheels don't ship,
so every compiled package (pydantic-core, numpy, ...) failed with
ModuleNotFoundError although its .pyd was installed.

The debug variant dates from when the plugin itself compiled against
Python.h. Since 3.0.0 only dart_bridge touches Python, through FFI, so every
build configuration now bundles python3XY.dll, python3.dll and
dart_bridge.dll, and the Dart side always opens dart_bridge.dll.

Subject: [PATCH 02/11] Drop CPython's debug modules from Windows Debug builds
 too

Every build configuration loads the release CPython now, so nothing imports
the *_d.pyd, *_d.dll and *_d.pdb files in DLLs/. Remove them from Debug
builds as well, not only from Release and Profile builds.
