  [Text Extraction] `replacementStrings` should apply case- and 
diacritic-insensitively
https://bugs.webkit.org/show_bug.cgi?id=317987
rdar://180636729

Reviewed by Abrar Rahman Protyasha.

Make several small adjustments to how client-specified `replacementStrings` 
works:

-   Make matching case-insensitive
-   Make matching diacritic-insensitive
-   Fold quotes when finding replacements
-   Apply longer replacements before shorter ones (so that a shorter 
replacement string that's
    contained in another longer replacement string doesn't cause the longer 
replacement string to
    not apply).

Tests:  TextExtractionTests.ReplacementStringsLongestMatchWins
        TextExtractionTests.ReplacementStringsCaseAndQuoteInsensitive
        TextExtractionTests.ReplacementStringsDiacriticInsensitive
