Errors from the base contracts can't be statically accessed from the inherited contracts

```solidity
abstract contract Base {
error TestError();
}

contract Top is Base {
function f() external {
revert TestError();
}
}

function test() pure {
// This is fine
revert Base.TestError();
}

function bug() pure {
// Error: Member "TestError" not found or not visible after argument-dependent lookup in type(contract Top).
revert Top.TestError();
}
```

Compile the minimal Solidity reproduction containing Base, Top, test, and bug, and inspect the compiler's member-lookup diagnostic for Top.TestError(). Trace how inherited custom errors are resolved when accessed through a derived contract. Done means the inherited error can be statically accessed as Top.TestError() while Base.TestError() and the existing revert in Top remain valid.
