Always evaluate free constants and statics, even if previous errors occurred

work towards rust-lang/rust#79738

We will need to evaluate static items before the `definitions.freeze()` below, as we will start creating new `DefId`s (for nested allocations) within the `eval_static_initializer` query.

But even without that motivation, this is a good change. Hard errors should always be reported and not silenced if other errors happened earlier.
