Fix exceptions in argparse #126068
Description
Bug report
There are several issues with exceptions in the argparse module:
- Only error messages for ArgumentError and ArgumentTypeError should be translated. These exceptions are the part of the user interface of the program that uses
argparse. Other exceptions indicate logical errors in the program and are purposed for the programmer. - ArgumentError should only be used for command line errors, not for logical errors in the program.

Even if some of this looks like bugs, I decided to not backport the change, because there is a small chance of user code depending on this. The benefit of making all right is not large, most users will not notice the change.
