Partial updates do not support incremental query

### Bug Description

**What happened:**
The incremental query does not return values for all columns in the table when we make a partial update; instead, it returns only the fields that changed as part of the partial update.

**What you expected:**
The incremental query should return all fields in the table. Due to this issue, we end up joining the table again to get the complete row, which is a performance hit.

### Environment
Table type
MOR
**Hudi version:**
Hudi 1.1
**Query engine:** (Spark/Flink/Trino etc)
Spark

### Logs and Stack Trace

_No response_

Start by reproducing the partial-update scenario described for a MOR table using Hudi 1.1 with Spark, then inspect the incremental query result. Done means the incremental query returns all table columns after a partial update, without requiring a join to recover unchanged fields.
