Detailed Description of the Pull Request / Additional comments

Changed the input sequence for Ctrl+Backspace to \x1b\x8 so the sequence would pass through _DoControlCharacter. Changed _DoControlCharacter to process \b in a way which forms the correct INPUT_RECORDs to delete whole words.

Validation Steps Performed

Ctrl+Backspace works 🎉
