Ever since we started using this at runtime it's been polluting the backtrace output. This makes it harder to debug errors and increases the amount of info users have to paste into the box when filing an issue. This is a very direct approach. Essentially, we strip out everything related to the `sorbet-runtime` gem whenever the top line in the backtrace is unrelated to sorbet-runtime. The hope is that this will allow errors related to sorbet to be diagnosed easily while also reducing the backtrace size for all other types of errors. Sometimes it is useful to see the full backtrace though. For those cases, we include the full backtrace when `--verbose` is passed in and print a warning that the Sorbet lines have been removed from the backtrace the first time they are removed. Note: This requires gems to be set up so that the call to `Gem.paths.home` works correctly. For that reason, it must be included after `utils/gems` which is included in `standalone/load_path` already.
