Rollup merge of #78669 - sasurau4:test/check-pass-consts, r=jyn514

Use check-pass instead of build-pass in some consts ui test suits

Helps with #62277

Changed tests modified by #57175 because of the stabilization `#![feature(const_let)]`.
They should be compile-fail because the feature gate checking disallow the feature before stabilization. So the feature gate checking have nothing to do with codegen according to https://rustc-dev-guide.rust-lang.org/feature-gate-ck.html.
