Hyukjin Kwon d4d6df2f7d [SPARK-26745][SQL] Revert count optimization in JSON datasource by SPARK-24959 
## What changes were proposed in this pull request?

This PR reverts JSON count optimization part of #21909.

We cannot distinguish the cases below without parsing:

```
[{...}, {...}]
```

```
[]
```

```
{...}
```

```bash
# empty string
```

when we `count()`. One line (input: IN) can be, 0 record, 1 record and multiple records and this is dependent on each input.

See also https://github.com/apache/spark/pull/23665#discussion_r251276720.

## How was this patch tested?

Manually tested.

Closes #23667 from HyukjinKwon/revert-SPARK-24959.
