[SPARK-53188][CORE][SQL] Support `readFully` in `SparkStreamUtils` and
`JavaUtils`
### What changes were proposed in this pull request?
This PR aims to support `readFully` in `SparkStreamUtils` and `JavaUtils`
which is based on Java 9+ `readNBytes` API.
```java
public static void readFully(InputStream in, byte[] arr, int off, int len)
throws IOException {
if (in == null || len < 0 || (off < 0 || off > arr.length - len)) {
throw new IllegalArgumentException("Invalid input argument");
}
if (len != in.readNBytes(arr, off, len)) {
throw new EOFException("Fail to read " + len + " bytes.");
}
}
```
### Why are the changes needed?
```scala
- ByteStreams.readFully(is, rowBuffer, 0, rowSize)
+ Utils.readFully(is, rowBuffer, 0, rowSize)
```
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Pass the CIs.
### Was this patch authored or co-authored using generative AI tooling?
No.
Closes #51915 from dongjoon-hyun/SPARK-53188.
