Address some of the sprintf in vcl/source/fontsubset/cff.cxx

...(which cause -Werror,-Wdeprecated-declarations with macOS 13 SDK), by making
CffSubsetterContext::getString, and in turn CffSubsetterContext::getGlyphName,
return OString.  Which in turn required adding rtl::OStringConstExpr and
OString::unacquired counterparts of rtl/ustring.hxx functionality to
rtl/string.hxx.

(It's not quite clear to me whether the nMaxLen clipping in
CffSubsetterContext::getString was only there to avoid overflow of the--
somewhat arbitrarily sized?---static aNameBuf, so could go now, or rather served
as a more general safety measure to not read past the mpReadPtr buffer end and
should thus remain.  Hence, I added a TODO comment for now.)
