Reintroduce OUString::replaceAt taking an OUString to LIBO_INTERNAL_ONLY

This allows optimizations when 'this' is empty, avoiding allocations, and
making it possible to not special-case it in other places, as was done in
ContentNode::Insert in commit 8ab44b114c6706ab2e3d8a19884daeb544d3c2e1
(tdf#161846 avoid allocation in ContentNode::Insert, 2024-07-30).

A couple of disambiguation templated overloads was introduced.
