Rollup merge of #93358 - compiler-errors:is-not-const, r=fee1-dead ...

Add note suggesting that predicate may be satisfied, but is not `const`

Not sure if we should be printing this in addition to, or perhaps _instead_ of the help message:
```
help: the trait `~const Add` is not implemented for `NonConstAdd`
```

Also added `ParamEnv::is_const` and `PolyTraitPredicate::is_const_if_const` and, in a separate commit, used those in other places instead of `== hir::Constness::Const`, etc.

r? ````@fee1-dead````
