TextFormat::ParseFieldValueFromString now takes absl::string_view as input instead of const std::string &

`TextFormat::ParseFieldValueFromString` would take `const std::string &` as the input, but it's a read-only string and immediately passed to `ArrayInputStream`. This CL will change it to `absl::string_view`.
