Revert "[libspirv] Define schar overloads via remangling; not source … (#18821)
…(#18626)" This reverts commit 23584c1. It exposed several issues not caught in pre-commit CI surrounding missing builtins, incorrect host selection of builtins, and remangling issues. I will add better tests for these before retrying.
