[interp] Disable mixed mode tests

When an exception is thrown from jitted code, the EH mechanism correctly sets the interp resume data to the right interp frame that should catch the exception, but it resumes to the interpreter by force, setting the MonoContext. This context has invalid data (for example the SP points to a InterpFrame and it is not the real sp at interp exit)

This bug was exposed by inlining changes from d3763c6c1e1971fce5863e0147dea74911ecb990
