5988: Postfix completions for fmt-like string literals r=matklad a=popzxc

This pull request adds a bunch of new postfix completions for `format`-like string literls.

For example, `"{32} {some_var:?}".println` will expand to `println!("{} {:?}", 32, some_var)`.

Postfix completions were added for most common format-like macros:

- `println` -> `println!(...)`
- `fmt` -> `format!(...)`
- `panic` -> `panic!(...)`
- `log` macros:
  + `logi` -> `log::info!(...)`
  + `logw` -> `log::warn!(...)`
  + `loge` -> `log::error!(...)`
  + `logt` -> `log::trace!(...)`
  + `logd` -> `log::debug!(...)`
