Fix (mis-)uses of temporary O[U]StringLiteral
...as sub-expressions of ternary operators, which happened to keep compiling
after 4b9e440c51be3e40326bc90c33ae69885bfb51e4 "Turn OStringLiteral into a
consteval'ed, static-refcound rtl_String" and
e6dfaf9f44f9939abc338c83b3024108431d0f69 "Turn OUStringLiteral into a
consteval'ed, static-refcound rtl_uString" because both branches are of the same
type O[U]StringLiteral<N>, and which didn't cause any issues because no dangling
pointers to those temporary objects escaped the surrounding full expressions.
This was found with an experimental build with VS 2022 with
--enable-latest-c++, which would support HAVE_CPP_CONSTEVAL after some linking
fix in the configure.ac detection code (which is forthcoming in a later commit)
and flagged all these uses in ternary operators as error C7595 "call to
immediate function is not a constant expression". That error looks bogus (and
it also caused a false
> sd/source/ui/unoidl/unoobj.cxx(742): error C7595: 'Color::Color': call to immediate function is not a constant expression
so HAVE_CPP_CONSTEVAL will need to remain undefined for VS 2022 until that
compiler bug is fixed), but it nicely found all these cases that should arguably
be cleaned up.
