hardware: qcom: sm7250: display: fix -Wreturn-stack-address
The return value of CompManager::StringDisplayList returns a pointer to
a local variable, whose lifetime ends at the end of that method. Fix
this by returning a std::string that will be copied (unless NRVO'd), and
pulling out the c_str() only when necessary.
