Disable <SelectField /> items based on predicate (closes #736)

[kestarumper]

This PR adds the ability to disable certain items based on predicate (similar to .filter(item => condition(item))) that can be specified as a prop.

Example: Disable all odd values

<SelectField
  name="x"
  disableItem={value => value % 2}
/>
