std.builtin: make `returnError` not take the error trace
It's now unnecessary to explicitly pass this, because it receives an implicit error trace parameter anyway, so can just use `@errorReturnTrace()`. The previous commit updated Sema to expect this new interface. This saves an AIR instruction at all `returnError` call sites.
