924060929 63a2344e68 [Enhancement](Nereids) Refactor AggregateFunction and support explain plan (#14380)
# Proposed changes

- Refactor AggregateFunction
    1. AggregateFunction implement ComputeSignature
    3. Add a CustomSignature to dynamic compute signature, we can check input type and compute implicit cast type in the `customSignature` method
    2. Add PartialAggType to record some type information before disassemble aggregate
    4. Refine and create a custom catalog function when translate AggregateFunction, without `finalizeForNereids`
-  Support explain plan
    1. explain parsed plan select ...
    5. explain analyzed plan select ...
    6. explain rewritten/logical plan select ...
    7. explain optimized/physical plan select ...
    8. explain all plan select ...
