[C++] Limit JSON max nesting depth #51757
Description
Describe the bug, including details regarding any error messages, version, and platform.
Arbitrarily nested JSON can run our JSON parser into a stack overflow.
We should hard-code the max JSON nesting depth to a reasonable value that's enough for any actual use case, and doesn't risk crashing.
