[Bug]: Missing Type Implementations in parseDefaultExpression for ClickHouseIO

### What happened?

The [parseDefaultExpression](https://github.com/apache/beam/blob/master/sdks/java/io/clickhouse/src/main/java/org/apache/beam/sdk/io/clickhouse/TableSchema.java#L315) function is missing implementations for the following ClickHouse types:

* `DateTime`
* `Array` (including nested)
* `Tuple`
* `Float32`
* `Float64`
This omission results in errors or unhandled cases when attempting to parse default expressions for these types.

## Suggested Improvement:
Generalize the parseDefaultExpression function to handle any string-based conversion into the appropriate Java representation that ClickHouse expects. This would make the function more robust and capable of supporting future type additions without requiring frequent updates.

## Steps to Reproduce:

Call the parseDefaultExpression function with a value and a column type that matches any of the unsupported types listed above.
Observe that the function either fails or returns an incorrect result.
