`SchemaView.materialize_patterns()` does not account for `slot_usage`
If I have a schema that contains the following:

```yaml
# test.yaml
settings:
  generated_id: "[a-z0-9]{6,}"

classes:
  MyClass:
    slots:
      - id

slots:
  id:
    structured_pattern:
      syntax: "prefix:{generated_id}"
```

And I call the `materialize_patterns` method on a `SchemaView` instance for that schema, I see that the `pattern` meta-slot is populated as expected:

```python
>>> from linkml_runtime import SchemaView
>>> view = SchemaView('test.yaml')
>>> view.schema.slots['id'].pattern is None
True
>>> view.materialize_patterns()
>>> view.schema.slots['id'].pattern
'prefix:[a-z0-9]{6,}'
```

However if the `structured_pattern` is instead set on the `slot_usage` of a class:

```yaml
# test2.yaml
settings:
  generated_id: "[a-z0-9]{6,}"

classes:
  MyClass:
    slots:
      -id
  FancyIdClass:
    is_a: MyClass
    slot_usage:
      id:
        structured_pattern:
          syntax: "prefix:{generated_id}"

slots:
  id:
```

Calling `materialize_patterns` on the `SchemaView` instance doesn't seem to have any effect. I suppose I would expect the `pattern` to be materialized on the `slot_usage` definition instead in this case.

```python
>>> view = SchemaView('test2.yaml')
>>> view.schema.classes['FancyIdClass'].slot_usage['id'].pattern is None
True
>>> view.materialize_patterns()
>>> # I think I would expect this to not be None at this point
>>> view.schema.classes['FancyIdClass'].slot_usage['id'].pattern is None
True
```
