[3.15] gh-151253: Dump the Python path configuration on _PyCodec_InitRegistry() failure (#151250) (#151269)
gh-151253: Dump the Python path configuration on _PyCodec_InitRegistry() failure (#151250)

If "import encodings" fails at Python startup, dump the Python path
configuration to help users debugging their configuration. The
encodings module is the first module imported during Python startup.
