Revert "Check UDT enum integer must derive from Copy (#1264)" (#1283)

### What

This reverts commit e43b3db.

### Why

It only works if the `derive` attribute comes after the `contracttype`
and is contained in a single list.
i.e. below works
```
#[contracttype]
#[derive(Clone, Copy, PartialEq, Eq, Debug)]
pub enum MyType
```
but these two don't
```
#[derive(Clone, Copy, PartialEq, Eq, Debug)]
#[contracttype]
pub enum MyType
```
```
#[contracttype]
#[derive(Clone, Copy)]
#[derive(PartialEq, Eq, Debug)]
pub enum MyType
```

### Known limitations

[TODO or N/A]
