bpo-42700: Swap descriptions in pyexpat.errors (GH-23876)
The descriptions of the `codes` and `messages` dictionaries in
`xml.parsers.expat.errors` were swapped, and this commit swaps them
back. For example, `codes` maps string descriptions of errors to numeric
error codes, not the other way around.
