Seeing the full type of the error is sometimes essential to diagnosing the problem, but the type itself is too long to be displayed in the terminal in a useful fashion. This change solves this dilemma by writing the full offending type name to a file, and displays this filename as a note.

note: the full type name been written to '$TEST_BUILD_DIR/issues/issue-22638/issue-22638.long-type.txt'

Closes #76777

Writing a file as part of diagnostics is novel AFAICT, but seems like the right thing to do in this case. One question, will cargo clean remove this?

The path is chosen by an existing function for temp files (it's very handy that rustc already has that), and cargo clean does clean it properly.
