Deprecate ExprSchemable:: data_type_and_nullable

[alamb]

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

datafusion/datafusion/expr/src/expr_schema.rs

Lines 426 to 443 in 4f95e6d

	/// Returns the datatype and nullability of the expression based on [ExprSchema].
	///
	/// Note: [`DFSchema`] implements [ExprSchema].
	///
	/// [`DFSchema`]: datafusion_common::DFSchema
	///
	/// # Errors
	///
	/// This function errors when it is not possible to compute its
	/// datatype or nullability.
	fn data_type_and_nullable(
	&self,
	schema: &dyn ExprSchema,
	) -> Result<(DataType, bool)> {
	let field = self.to_field(schema)?.1;
	Ok((field.data_type().clone(), field.is_nullable()))
	}

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
