Noel Grandin 6f8073caf0 tdf#158773 reduce cost of ContentInfo::GetText
The specific path that is showing up on the perf profile is

SdrTextObj::HasText -> EditTextObjectImpl::GetText ->
ContentInfo::GetText

Reduce the cost by 10% there by adding a method to check if we have text, and
avoid the cost of constructing an OUString from an svl::SharedString.

Also make use of the new method in places.
