[SPARK-22597][SQL] Add spark-sql cmd script for Windows users

## What changes were proposed in this pull request?

This PR proposes to add cmd scripts so that Windows users can also run `spark-sql` script.

## How was this patch tested?

Manually tested on Windows.

**Before**

```cmd
C:\...\spark>.\bin\spark-sql
'.\bin\spark-sql' is not recognized as an internal or external command,
operable program or batch file.

C:\...\spark>.\bin\spark-sql.cmd
'.\bin\spark-sql.cmd' is not recognized as an internal or external command,
operable program or batch file.
```

**After**

```cmd
C:\...\spark>.\bin\spark-sql
...
spark-sql> SELECT 'Hello World !!';
...
Hello World !!
```
