Unicode: fix the grapheme clustering algorithm
An oversight in the code kept the algorithm in the GB11 state, even if
the codepoint that is being processed wouldn't allow for that (for
instance a sequence of ExtPic, Ext and Any).
Refactor the code of GB11/GB12/GB13 to deal with code points that break
the sequences (falling back to "normal" handling).
Add some manual tests; interestingly enough, the failing cases are not
covered by Unicode's tests, as we now pass the entire test suite.
