Merge #19004: refactor: Replace const char* to std::string
c57f03ce1741b38af448bec7b22ab9f8ac21f067 refactor: Replace const char* to std::string (Calvin Kim)
Pull request description:
Rationale: Addresses #19000
Some functions should be returning std::string instead of const char*.
This commit changes that.
Main benefits/reasoning:
1. The functions never return nullptr, so returning a string makes code at call sites easier to review (reviewers don't have to read the source code to verify that a nullptr is never returned)
2. All call sites convert to string anyway
