cmake: restore variable names `CURL_CA_BUNDLE_SET`/`CURL_CA_PATH_SET`

They were renamed recently as internal variables, but they are both
cached, so let's keep the original names for consistency and
compatibility.

Partial revert of c2889a7b4180fc963ae30811f59ab547b6eb03cd #14388
Tested via #14778
