This commit modifies `check_attr` so that:
- Enum variants are now checked (some attributes would not have been
prohibited on variants previously).
- `check_expr_attributes` and `check_stmt_attributes` are removed as
`check_attributes` can perform the same checks.

Fixes#47094
Besides fixing that bug, this change has a user-visible effect on the spans in the "incompatible repr hints" warning and another error: they now point at `foo` and/or `bar` in `repr(foo, bar)` instead of the whole attribute. This is sometimes more precise (e.g., `#[repr(C, packed)]` on an enum points at the `packed`) but sometimes not. I moved a compile-fail test to a ui test to illustrate how it now looks in the common case of only one attribute.
