Fuzz JSON table function
...
Create a table function `fuzzJSON`
An example query:
```
CREATE NAMED COLLECTION json_fuzzer AS json_str={};
SELECT *
FROM fuzzJSON(json_fuzzer, json_str = '{"students" : ["Alice", "Bob"]}', random_seed = 666, max_output_length = 128, probability = 0.9)
LIMIT 3
Query id: 7f802052-efb0-41b4-87fa-03b7dd290e9d
┌─json──────────────────────────────────────────────────────────────────────────────────┐
│ {"ade0yX":[9200406572736542991, true, "sm"]} │
│ {"students":["Alice", "eSN3WO#a6NYTBe0$#OWwyIQ"], "cVoP2BuQugQ":17384271928263249403} │
│ {"students":["Alice", "Bob", "T+-k4+PJGkL%XRRaF2BoeN@&A"]} │
└───────────────────────────────────────────────────────────────────────────────────────┘
```
Next step:
* Generate invalid string
Fixes #35962
add Object('json')
use named collection
