Add lint panic in result

### Change
Adding a new "restriction" lint that will emit a warning when using "panic", "unimplemented" or "unreachable" in a function of type option/result.

### Motivation
Some codebases must avoid crashes at all costs, and hence functions of type option/result must return an error instead of crashing.

### Test plan
Running:
TESTNAME=panic_in_result cargo uitest ---
