Description of changes

To work around intermitent build failures with clang 16, the stdenv attempted to pass arguments on the command-line on newer versions of macOS. Unfortunately, the larger ARG_MAX is still not large enough to build qtwebengine. This commit reverts the NIX_CC_NO_RESPONSE_FILE logic in the stdenv. The changes to cc-wrapper in #245282 are needed for clang 16 to prevent the above-mentioned build failures.
