This reverts commit eea38787b9 from PR #34242
We do not need comparators for HTTPHeaders since it is not using unordered_map anymore.
We only need a simple, locale-independent, ascii-only compare function for
a vector of key-value pairs of strings.
We have CaseInsensitiveEqual already in test utils, this commit moves
it to the strencodings module for use in the application code.
