Spellchecker: resolve warnings (#42202)

## Summary of the Pull Request

This PR resolves lingering spell-check warnings and other minor issues,
allowing us to focus on newly emerging problems.

**Changes:**

- Excludes empty and binary files  
- Converts invalid dictionary entries into patterns  
- Since dictionary entries can only contain letters, `0x6f677548` was
previously ignored
- Removes unused words  
- Adds a pattern marker to ignore all code on a line  
  - `/* #no-spell-check-line */`  
  - `// #no-spell-check`  

This should reduce outstanding spellchecker warnings and suggestions to
zero.
