…et and truncate functions in Gravitino SortOrder (apache#2928) Add width param to bucket and truncate functions in Gravitino SortOrder. for example: change `bucket([id]) `to `bucket(10, id)` change `truncate([name]) `to `truncate(2, name)` SortOrder in Iceberg supports `FunctionExpression`, such as `year, month, bucket, truncate, etc`. `truncate` and `bucket` functions both have two parameters, such as `bucket(10, col1), truncate(2, col2)`. However, in gravitino, when converting an iceberg sortorder with `bucket` or `truncate` to gravitino sortOrder, there is only one parameter in `bucket` and `truncate` functions. This picture shows the details of the parameters of the `bucket` and `truncate` functions in gravitino sortorder, we can test it in `com.datastrato.gravitino.catalog.lakehouse.iceberg.converter.TestFromIcebergSortOrder#testFromSortOrder`  And if we want to convert the gravitino sortOrder with `bucket` or `truncate` to iceberg sortOrder, we will get the following error as the first param is missing. ``` java.lang.IllegalArgumentException: Bucket sort should have 2 arguments at com.google.common.base.Preconditions.checkArgument(Preconditions.java:143) at com.datastrato.gravitino.catalog.lakehouse.iceberg.converter.ToIcebergSortOrder.toSortOrder(ToIcebergSortOrder.java:56) at com.datastrato.gravitino.catalog.lakehouse.iceberg.converter.TestFromIcebergSortOrder.testFromSortOrder(TestFromIcebergSortOrder.java:86) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.platform.commons.util.ReflectionUtils.invokeMethod(ReflectionUtils.java:725) at org.junit.jupiter.engine.execution.MethodInvocation.proceed(MethodInvocation.java:60) ``` Fix: apache#2921 No New UTs and ITs.

What changes were proposed in this pull request?
Add width param to bucket and truncate functions in Gravitino SortOrder.
for example:
change
bucket([id])tobucket(10, id)change
truncate([name])totruncate(2, name)Why are the changes needed?
SortOrder in Iceberg supports
FunctionExpression, such asyear, month, bucket, truncate, etc.truncateandbucketfunctions both have two parameters, such asbucket(10, col1), truncate(2, col2).However, in gravitino, when converting an iceberg sortorder with
bucketortruncateto gravitino sortOrder, there is only oneparameter in
bucketandtruncatefunctions.This picture shows the details of the parameters of the
bucketandtruncatefunctions in gravitino sortorder, we can test it incom.datastrato.gravitino.catalog.lakehouse.iceberg.converter.TestFromIcebergSortOrder#testFromSortOrderAnd if we want to convert the gravitino sortOrder with
bucketortruncateto iceberg sortOrder, we will get the following error as thefirst param is missing.
