5da28bd3 - [clang-tidy][NFC] Make a few `std::string`s into `StringRef`s (#160961)

[clang-tidy][NFC] Make a few `std::string`s into `StringRef`s (#160961) Following up 12cb540. Also, that commit left behind a few cases where a temporary `StringRef` was being constructed from those variables just to use its `.split()` function, so this PR cleans those up too.
