[I] Deprecate ExprSchemable:: data_type_and_nullable [datafusion]
alamb opened a new issue, #18844:
URL: https://github.com/apache/datafusion/issues/18844
### Is your feature request related to a problem or challenge?
ExprSchemable::datatype_and_properties simply calls through to `to_field` and thus makes the API more complicated for no real gain
https://github.com/apache/datafusion/blob/4f95e6d70249d0d839939facc67f95cd7f54526e/datafusion/expr/src/expr_schema.rs#L426-L443
### Describe the solution you'd like
We should deprecate `data_type_and_nullable` to encourage people to use `to_field` directly
The deprecation guidelines are here: https://datafusion.apache.org/contributor-guide/api-health.html#deprecation-guidelines
