target/xtensa: don't generate extra EXCP_DEBUG on exception
target/xtensa used to generate an extra EXCP_DEBUG exception before the
first instruction executed after an interrupt or an exception is taken
to allow single-stepping that instruction in the debugger.
This is no longer needed after the following commits:
a7ba744f4082 ("tcg/cpu-exec: precise single-stepping after an exception")
ba3c35d9c402 ("tcg/cpu-exec: precise single-stepping after an interrupt")
Drop exception state tracking/extra EXCP_DEBUG generation code.
