8f2589b3b0 LibUnicode: Parse and generate case folding code point data 
Case folding rules have a similar mapping style as special casing rules,
where one code point may map to zero or more case folding rules. These
will be used for case-insensitive string comparisons. To see how case
folding can differ from other casing rules, consider "ß" (U+00DF):

    >>> "ß".lower()
    'ß'

    >>> "ß".upper()
    'SS'

    >>> "ß".title()
    'Ss'

    >>> "ß".casefold()
    'ss'

bc51017a03 LibUnicode: Support full case folding for titlecasing a string 
Unicode declares that to titlecase a string, the first cased code point
after each word boundary should be transformed to its titlecase mapping.
All other codepoints are transformed to their lowercase mapping.

12f6793223 LibUnicode: Move Unicode-aware case transformations to a helper file 
These will be needed by AK::String as well, so move them to a helper
file where they can be re-used.
