WIP: clang-tidy fixes around const std::string references.
Description
This is the clang-tidy
fixes that @luk036 had in his pull request at https://github.com/verilog-to-routing/vtr-verilog-to-routing/pull/1078
These changes make the code follow closer to best practices around using const std::string references.
This change isn't quite ready to be merged yet as it currently includes changes to code under libs/EXTERNAL
. These need to be extracted out of the pull request and sent to the appropriate external projects.
@luk036 : feedback from @hzeller on these clang-tidy changes. Looks like we'd only want a subset of them.
