Add CONST_ITEM_MUTATION lint
Fixes #74053 Fixes #55721 This PR adds a new lint `CONST_ITEM_MUTATION`. Given an item `const FOO: SomeType = ..`, this lint fires on: * Attempting to write directly to a field (`FOO.field = some_val`) or array entry (`FOO.array_field[0] = val`) * Taking a mutable reference to the `const` item (`&mut FOO`), including through an autoderef `FOO.some_mut_self_method()` The lint message explains that since each use of a constant creates a new temporary, the original `const` item will not be modified.
