chore: Clean up build (#5519)

This PR contains 3 minor changes that improve the general build
experience.

* `.gitignore` is updated to exclude certain files that seem to be
generated by the C++ compiler.
* The `pre-commit` script that enforces C# coding style is updated to
exclude Dafny-generated C# code.
* The invisible characters (probably ones that say something about the
UTF encoding of text files) at the beginning of some `.expect` files are
removed. The tests now pass both through Rider's test mechanisms and
through `lit` on the command line.
