Improve S2222: Expect operations to throw outside try statement

[pavel-mikula-sonarsource]

Description

Expect operations to throw exception also outside try statement.

Monitor.Enter(obj);  // Noncompliant
SomethingThatCanThrow();
Monitor.Exit(obj);

How

Implementation is easy

           if (exceptionCandidate.FromOperation(node.Operation) is { } exception)
            {
                foreach (var successor in ExceptionSuccessors(node, exception, node.Block.EnclosingRegion(ControlFlowRegionKind.Try)))

The affect on our test framework is big. As a prerequisite, we need to change the way Tag("") asserting works.

Change is scaffolded in a branch https://github.com/SonarSource/sonar-dotnet/tree/Pavel/SE-ExceptionsOutsideTry but many UTs needs polishing to make it run. The test framework update should be done in few PRs as a prerequisite:

• Extend the functionality and migrate some test case
• Migrate all usages
• Implement this ticket
