IMPALA-10237: Support Bucket and Truncate partition transforms as built-in functions

This patch implements Truncate and Bucket partition transforms in Impala BE as
built-in functions. The expectation is that these functions give the same
result as Iceberg's implementation of the same functions. These built-in
functions are invisible so users won't be able to invoke them e.g. from
impala-shell.

Truncate:
  - Supported types are IntVal, BigIntVal, StringVal, DecimalVal.
  - Receives an input from the above types and a width.
  - Returns the same type as the input.
  - Expected behaviour is explained here:
    https://iceberg.apache.org/spec/#truncate-transform-details
Bucket:
  - Supported types are IntVal, BigIntVal, StringVal, DecimalVal, DateVal,
    TimestampVal.
  - Receives an input from the above types and the number of buckets as IntVal.
  - Returns IntVal.
  - Expected behaviour is explained here:
    https://iceberg.apache.org/spec/#bucket-transform-details
