## Description
<ins>Problem</ins>
When we have a `select/multi-select` field type and the source data
gives empty array to the `JSONFormWidget`, the widget tries to gauge the
sub type for value inside the array, and since it is empty it got
`undefined`
This led to re-evaluation of property config for the field.
<ins>Solution</ins>
- Added a check to prevent unnecessary recalculation of sub data types
when arrays are empty in `checkIfArrayAndSubDataTypeChanged`.
- Changed parameter type from `any` to `unknown` in `dataTypeFor` and
`subDataTypeFor` functions for improved type safety.
- Added and refactored unit tests.
This refactor enhances type safety and optimizes performance in the
schema parsing logic.
