[debugger] Debugger doesn't break on unhandled exceptions (mono/mono#15234)

[debugger] Debugger doesn't break on unhandled exceptions  (mono/mono#15234)

* When the catch found is in a MONO_WRAPPER_RUNTIME_INVOKE the exception should be treated as an UNHANDLED by the debugger.

* Adding unit test.

* trying to fix side effect.

* I've tested the MonoTests.DebuggerTests.UnhandledException_2 test on VsWin using .net Framework and I think the test is wrong because the first break is in throw and the next break will be on breakpoint.
In our implementation we were ignoring the unhandled exception and stopping only on breakpoint.
