Summary: CAST(JSON as ROW(ARRAY()) used to fail with ``` OUT_OF_ORDER_ITERATION: Objects and arrays can only be iterated when they are first encountered. ``` According to simdjson documentation, https://github.com/simdjson/simdjson/blob/master/doc/basics.md, it is not allowed to store object values for later processing. These must be consumed or copied before proceeding. Also, fixed behavior when JSON object contains duplicate keys. Presto throws, but previous implementation used to allow duplicates. Also, fix the test to actually verify JSON objects with mixed case keys. Differential Revision: D56013293

nit: RowType::size is virtual and may not be able to inline here, so better assign it to a variable before loop

We could initialize fieldIndices value to -1 then we don't need this second memory.

Sounds good. Updated.
