tests/tcg/xtensa: conditionalize interrupt tests

Make interrupt tests conditional on the presence of interrupt option and
on the presence of level-1 and high level software interrupts. Don't use
hard-coded interrupt level for the high level interrupt tests, choose
high level software IRQ and use its configured level.
