Tools/ocr/v2 (#4055)

# Description of Changes

- Added the OCR tool 
- Added language mappings file to map selected browser language -> OCR

translation function to translate the languages rather than mapping them
to english be default
- Added chevron icons to tool step to show expand and collapsed state
more visibly
- Added a re-usable dropdown picker with a footer component
