[FEA] Leverage RECOVER_WITH_NULL when parsing JSON in from_json_to_raw_map

[ttnghia]

When from_json_to_raw_map was implemented, recovery with null was not possible thus the function always throws exception when the input is invalid. Now, with RECOVER_WITH_NULL supported, the problematic rows can be just ignored so output for the remaining rows can be processed normally. We should adopt RECOVER_WITH_NULL in from_json_to_raw_map accordingly.
