5171: Extract CConsole::TraverseChain, fix toggle with multiple chains r=def- a=Robyt3

Extract `CConsole::TraverseChain` (https://github.com/teeworlds/teeworlds/pull/2933).

Fix `toggle`/`+toggle` commands with commands which are chained multiple times.

## Checklist

- [X] Tested the change ingame
- [ ] Provided screenshots if it is a visual change
- [ ] Tested in combination with possibly related configuration options
- [ ] Written a unit test if it works standalone, system.c especially
- [ ] Considered possible null pointers and out of bounds array indexing
- [ ] Changed no physics that affect existing maps
- [ ] Tested the change with [ASan+UBSan or valgrind's memcheck](https://github.com/ddnet/ddnet/#using-addresssanitizer--undefinedbehavioursanitizer-or-valgrinds-memcheck) (optional)
