Clang-tidy, fix bugprone-exception-escape.

Remove redundant call to `ofstream::close()` from `~PSStrokeRenderer`
and `~TextStrokeRenderer`. ofstream will be destructed automatically.

- For `~Depsgraph`, `std::function`'s constructor can throw.
- Passing throwing statements in the lambda will not be detected by
  clang-tidy.
Fix these issues by using lambda as function argument.
