Remove more c_str with SetFileName string overload

Summary

• Make readers' and writers' SetFileName string overload the main one, and make const char* call it (instead of the over way around)
• Remove 53 calls to c_str using:

find Modules/ Examples/ -type f -print0 | xargs -0 sed -i -E "s/SetFileName\((.*)\.c_str\(\)/SetFileName\(\1/"

Rationale

#513 (closed), the hunt for c_str

Implementation Details

Also replace some method type signatures with const string reference instead of string by value. Also adds the missing file otbWrapperOutputVectorDataParameter.cxx and move WrapperOutputVectorDataParameter code from the .h to the .cxx.
