49f2e1dc64 neotest: gracefully report about coverage setup error 
Don't use panic when we can use t.Fatal.

2dc588ea95 neotest: distinguish coverage modes 
Use calls frequency calculated by executor in the final coverage
profile for `atomic` cover mode. Support only `set` cover mode for now
due to #3587.

7fac3bcd6f neotest: don't collect coverage for contracts with empty DI 
Users are allowed to provide any contract to neotest, including those
contracts that don't have DebugInfo filled in. Neotest should filter
them out, otherwise panic may occur on attempt to write coverage profile:
```

d0c45477f5 neotest: implement coverage collection 
Test coverage is automatically enabled when go test is running with coverage
enabled. It can be disabled for any Executor by using relevant methods.
Coverage is gathered by capturing VM OPs during test contract execution and
mapping them to the contract source code using the DebugInfo information.
