Otherwise we run into a panic in hscMaybeWriteIface: "Unexpected DT_Dyn state
when writing simple interface" when dynamic-too is enabled
We could remove the panic and just write the interface even if the state is `DT_Dyn`,
but it seems pointless to run the pipeline twice when `hscMaybeWriteIface` is already
designed to write both `hi` and `dyn_hi` files if dynamic-too is enabled.
Fixes #23944.

This patch does two things, to fix #23209:
* It improves SpecConstr so that it no longer quantifies over
coercion variables. See Note [SpecConstr and casts]
* It improves the rule matcher to deal nicely with the case where
the rule does not quantify over coercion variables, but the the
template has a cast in it. See Note [Casts in the template]
