[Text] Add support for titlecasing decomposed ligatures
https://bugs.webkit.org/show_bug.cgi?id=283754
<rdar://problem/140658460>
Reviewed by Antti Koivisto.
Replace u_totitle with u_strToTitle to support titlecasing decomposed ligatures.
When the candidate character has ligature (fi) while the titlecased version does
not (Fi),
u_totitle fails to make the conversion, while u_strToTitle simply tells us to
expand
the output buffer to be able to hold the enlarged content.
Using u_strToTitle also enables us to handle non-BPM content and support local
(FIXME).
(We can't just apply u_strToTitle on the entire content as, in addition to
titlecasing the first character, it also lowercases all others which is not
what 'text-transform: capitalize' expects. see
https://unicode-org.github.io/icu-docs/apidoc/dev/icu4c/ustring_8h.html#a47602e2c2012d77ee91908b9bbfdc063)
imported/blink/fast/forms/select/select-text-transform.html -> progression.
LayoutTests/fast/css/text-transform-select.html is exactly the same as
select-text-transform.html (see above) but with render tree dump -> remove.
