config: Config error limit/hyprctl (#5165)

* Add error_limit to limit the number of config error messages shown in notification

* Add configerrors hyprctl command

* Formatting

* Formatting for not my code

* Use CVarList, add escapeJSONStrings

* Add indication there are more undisplayed errors

* Restore suppress_errors; move getErrors() to ConfigManager

* Formatting, wtf

* Format
