superpmi: Catch errors while printing the unicode string

[kunalspathak]

In #64251, I made a fix to catch decoding issues, but seems that the problem also occurs when printing those characters. On quick search reveals this problem and proposals to fix them, but the simplest thing to do in our situation would be to just return empty string if such errors occur. So, I converted the decode_string method to decode_and_print which will catch the printing errors as well.

Fixes: #64575

I wonder if maybe it should return something like <unicode conversion error>, but maybe it doesn't matter.
