87ddc1ea33 Point at generic param through which a const is used in a pattern
```
error[E0158]: constant pattern depends on a generic parameter, which is not allowed

   |             - constant depends on this generic param

   |         ^^^^ `const` depends on a generic parameter

c6205055e0 On const pattern errors, point at the const item definition
Centralize emitting an error in `const_to_pat` so that all errors from that evaluating a `const` in a pattern can add addditional information. With this, now point at the `const` item's definition:

```
error[E0158]: constant pattern depends on a generic parameter
  --> $DIR/associated-const-type-parameter-pattern.rs:20:9
   |
LL | pub trait Foo {
   | -------------
LL |     const X: EFoo;
   |     ------------- constant defined here
...
LL |         A::X => println!("A::X"),
   |         ^^^^
```
