[WIP][DO NOT LAND] Componentize spellcheck

 //
 // The |FeedbackSender| object stores the user feedback to spellcheck
 // suggestions in a |Feedback| object.
 //
 // When spelling service returns spellcheck results, these results first arrive
 // in |FeedbackSender| to assign hash identifiers for each
 // misspelling-suggestion pair. If the spelling service identifies the same
 // misspelling as already displayed to the user, then |FeedbackSender| reuses
 // the same hash identifiers to avoid duplication. It detects the duplicates by
 // comparing misspelling offsets in text. Spelling service can return duplicates
 // because we request spellcheck for whole paragraphs, as context around a
 // misspelled word is important to the spellcheck algorithm.
 //
 // All feedback is initially pending. When a user acts upon a misspelling such
 // that the misspelling is no longer displayed (red squiggly line goes away),
 // then the feedback for this misspelling is finalized. All finalized feedback
 // is erased after being sent to the spelling service. Pending feedback is kept
 // around for |kSessionHours| hours and then finalized even if user did not act
 // on the misspellings.
 //
 // |FeedbackSender| periodically requests a list of hashes of all remaining
 // misspellings in renderers. When a renderer responds with a list of hashes,
 // |FeedbackSender| uses the list to determine which misspellings are no longer
 // displayed to the user and sends the current state of user feedback to the
 // spelling service.
