[SPARK-30653][INFRA][SQL] EOL character enforcement for java/scala/xml/py/R files
### What changes were proposed in this pull request?
This patch converts CR/LF into LF in 3 source files, which most files are only using LF. This patch also add rules to enforce EOL as LF for all java, scala, xml, py, R files.
### Why are the changes needed?
The majority of source code files are using LF and only three files are CR/LF. While using IDE would let us don't bother with the difference, it still has a chance to make unnecessary diff if the file is modified with the editor which doesn't handle it automatically.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
```
grep -IUrl --color "^M" . | grep "\.java\|\.scala\|\.xml\|\.py\|\.R" | grep -v "/target/" | grep -v "/build/" | grep -v "/dist/" | grep -v "dependency-reduced-pom.xml" | grep -v ".pyc"
```
(Please note you'll need to type CTRL+V -> CTRL+M in bash shell to get `^M` because it's representing CR/LF, not a combination of `^` and `M`.)
Before the patch, the result is:
```
./sql/core/src/main/java/org/apache/spark/sql/execution/columnar/ColumnDictionary.java
./sql/catalyst/src/test/scala/org/apache/spark/sql/catalyst/optimizer/complexTypesSuite.scala
./sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/optimizer/ComplexTypes.scala
```
and after the patch, the result is None.
And git shows WARNING message if EOL of any of source files in given types are modified to CR/LF, like below:
```
warning: CRLF will be replaced by LF in sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala.
The file will have its original line endings in your working directory.
```
Closes #27365 from HeartSaVioR/MINOR-remove-CRLF-in-source-codes.
