This prints out human-readable error messages for failures.

As an example, FT2Font("setup.py") now raises

RuntimeError: In FT2Font: Can not load face (unknown file format; error code 0x2)

(sure, this specific error was special-cased before, but that's not the case for e.g. #22212, which is the motivation for this PR.)

Modulo clarifying the comment. Can self merge after that.
