…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.
