Convert an object to a nanoarrow schema

Description

In nanoarrow a 'schema' refers to a ⁠struct ArrowSchema⁠ as defined in the Arrow C Data interface. This data structure can be used to represent an arrow::schema(), an arrow::field(), or an arrow::DataType. Note that in nanoarrow, an arrow::schema() and a non-nullable arrow::struct() are represented identically.
