CLDR-17582 Cleanup English annotations

[macchiati]

CLDR-17582

• This cleans up the English annotations according to the directions given to vetters.
• The multiword search keys are split up.
• Duplicates (or near duplicates), synonyms, and low-value terms are removed.
  • or at least reduced, with a focus on items that had a very large number of annotations.
• Reduce the maximum number of search terms on items.
• Other misc. cleanup.

When reviewing, note that breaking up keywords and then alphabetizing means that phrases are distributed. Example:

• cp="😄"
• old: awesome | face | grin | grinning face with big eyes | happy | mouth | open | smile | smiling | smiling face with open mouth | teeth | yay
• new: awesome | big | eyes | face | grin | grinning | happy | mouth | open | smile | smiling | teeth | yay

We can't expect a line-by-line review, so please just spot-check looking for anything that is terrible: We can tweak the English later on before release; the goal here is to adhere more to the guidelines to lessen the chances vetters will be misled (though we caution them that they need to look at the associations in their languages, not English!)

• [ ] This PR completes the ticket.
