Move isIVSSelector, isCJKIVSCharacter to i18nutil/unicode.hxx

6a7db071c75609093fc3a9cbc297b8069726a33e "tdf#125497 allow backspace to remove
CJK IVS" had moved these functions from sw/source/uibase/wrtsh/delete.cxx to
rtl/character.hxx, but the latter appears to be a less than ideal home for them:
For one, it is part of the stable URE interface, which makes it harder to
maintain (e.g., later versions of Unicode have added CJK Extension C--F code
blocks, which the current implementation of isCJKIVSCharacter does not reflect).
And for another, besides details of legacy/ubiquitous ASCII, it only deals with
the "hard" structure of Unicode (isUnicodeCodePoint, isSurrogate, etc.), not
with any specific code blocks or character classifications (which can change
over time).  Internal i18nutil/unicode.hxx appears to be better suited.
