std.builtin: make returnError not take the error trace

Browse Source 
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.
