Add compiled cython and virtual environments in gitignore

[tobiasdiez]

As preparation for #30371, the gitignore file is extended to ignore compiled cython files (e.g. *.so) as well as the virtual environments (e.g. src/.venv). These changes are more or less copied from https://www.toptal.com/developers/gitignore/api/python,visualstudiocode.

Finally, I've also taken the opportunity to change to comments to a consistent format (simple single line comments).

Depends on #30730

This vscode configuration does not make sense without #30371. In a normal Sage build, the venv directory is local/.

Best to have two separate tickets for two separate issues.

Also, these ones here are not correct because we do have a few *.c and *.cpp files that should not be .gitignored.

Remove VS code settings, and add exceptions for already checked-in files

Ok, I've added the already checked-in C/C++ files as exceptions. Also moved the VS code settings files to the new ticket #30677.

Moreover, its recommended to checkin some VS Code config files (which makes it easier for new users to start developing), so I did this.

It would be nice if this could be reviewed and merged rather quickly, as it's hard for me to work on other branches right now because of the large number of untracked files (>5k) coming from the editable install.

I'll merge in #30730 (which is on its way into the next rc) to resolve a merge conflict
