Explicitly define conditional LOB constructors for const (w)string &

Browse Source 
This fixes compilation against libcxx 19, which removed the
non-standard specializations for std::char_traits including the one
for unsigned char, which would get instantiated for BLOB.
See https://reviews.llvm.org/D138307 and
https://reviews.llvm.org/D157058.

Closes #4722.
