Add builder style APIs For Field: with_name, with_data_type and with_nullable

[alamb]

Which issue does this PR close?

Closes #1934

Rationale for this change

The lack of such an API caused me consternation in apache/datafusion#2803 and https://github.com/influxdata/influxdb_iox/pull/5021

Basically I want to be able to change a field's nullability like

let new_field = old_field.clone().with_nullable(false);

But instead I have to do something like

 // make a copy of the field, but allow it to be nullable
 Field::new(f.name(), f.data_type().clone(), true)
   .with_metadata(f.metadata().cloned())

What changes are included in this PR?

1. Add Field::with_name
2. Add Field::with_data_type
3. Add Field::with_nullability
4. Add examples (which also serve as tests)
5. Update additional documentation

Are there any user-facing changes?

yes, new APIs and better docs

LGTM!
Nit: It seems like the 3 methods are not covered in the Codecov result, although they have been tested by docs.
