Rollup merge of #88851 - fee1-dead:dup-bound, r=oli-obk 
Fix duplicate bounds for const_trait_impl

Fixes #88383.

Compare the constness of the candidates before winnowing and removing a `~const` `BoundCandidate`.

Rollup merge of #88709 - BoxyUwU:thir-abstract-const, r=lcnr 
generic_const_exprs: use thir for abstract consts instead of mir

Changes `AbstractConst` building to use `thir` instead of `mir` so that there's less chance of consts unifying when they shouldn't because lowering to mir dropped information (see `abstract-consts-as-cast-5.rs` test)
