chore: remove unused deriving handler argument syntax (#5265) 
As far as I can tell, the ability to pass a structure instance to a
deriving handler is not actually used in practice. It didn't seem to be
used in the test suite, at least.

Do we want to remove this, or do we want to use and document it? This PR
removes it, but that's not something I feel strongly about - but seeing
if it breaks Mathlib is a useful data point.
