fix: Support JSON default values in FillFieldData (#45455)

Browse Source 
Related to #45445

Previously, FillFieldData for JSON fields would assert and fail when a
default_value was provided, blocking index creation for JSON fields with
default values (including dynamic fields like $meta).

This change enables JSON default value support by:
- Removing the assertion that blocked default values
- Parsing bytes_data into Json objects when default_value is present
- Properly filling data_ array and setting valid_data_ bitset to true
- Maintaining null behavior when no default_value is provided

Impact:
- Fixes index creation failure for JSON fields with default values
- Resolves upgrade issues from 2.5 to 2.6.5 where dynamic fields with
default values couldn't be indexed
- Index builds that were stuck in InProgress state can now complete
