Support date types in `percentile_cont` aggregate function

### Is your feature request related to a problem or challenge?

https://github.com/apache/datafusion/pull/17988 has added support for `percentile_cont`, and this function can support more date-related data types.

Data is generated with https://github.com/clflushopt/tpchgen-rs/tree/main/tpchgen-cli
```
DataFusion CLI v51.0.0
> select percentile_cont(0.01) within group (order by l_shipdate)
from '/Users/yongting/data/tpch_sf1/lineitem.parquet';
Error during planning: Failed to coerce arguments to satisfy a call to 'percentile_cont' function: coercion from Date32, Float64 to the signature OneOf([Exact([Int8, Float64]), Exact([Int16, Float64]), Exact([Int32, Float64]), Exact([Int64, Float64]), Exact([UInt8, Float64]), Exact([UInt16, Float64]), Exact([UInt32, Float64]), Exact([UInt64, Float64]), Exact([Float32, Float64]), Exact([Float64, Float64])]) failed No function matches the given name and argument types 'percentile_cont(Date32, Float64)'. You might need to add explicit type casts.
Candidate functions:
percentile_cont(expr: Int8, percentile: Float64)
percentile_cont(expr: Int16, percentile: Float64)
percentile_cont(expr: Int32, percentile: Float64)
percentile_cont(expr: Int64, percentile: Float64)
percentile_cont(expr: UInt8, percentile: Float64)
percentile_cont(expr: UInt16, percentile: Float64)
percentile_cont(expr: UInt32, percentile: Float64)
percentile_cont(expr: UInt64, percentile: Float64)
percentile_cont(expr: Float32, percentile: Float64)
percentile_cont(expr: Float64, percentile: Float64)
```

Start at the percentile_cont aggregate-function implementation and its argument type-signature or coercion handling. Reproduce the shown DataFusion CLI query with the TPCH lineitem data, then add coverage for Date32 and the date-related types supported by the implementation. Done means percentile_cont accepts the reported date input and returns the expected percentile result.
