feat: allow erasing cbv_eval attributes (#12851) 
This PR add support for erasing `@[cbv_eval]` annotations using
`attribute [-cbv_eval]`, mirroring the existing `@[-simp]` mechanism for
simp lemmas.

The `CbvEvalEntry` now tracks the original declaration name (`origin`)
so that inverted theorems (`@[cbv_eval ←]`) can be erased by their
original name. The `CbvEvalState` stores individual entries alongside
the composed `Theorems` discrimination tree, allowing the tree to be
rebuilt from remaining entries after erasure. Erasure is properly scoped
via `modifyState`, so `attribute [-cbv_eval]` inside a `section` is
reverted when the section ends.
