set_exception_visitor: Remove the special case for wasi proc exit (#2525)

Browse Source 
While wasi proc exit is not a real trap, what the runtime does on it is mostly same as
real traps. That is, kill the siblings threads and represent the exit/trap as the result of
the "process" to the user api. There seems no reason to distinguish it from real traps
here.

Note that:
- The target thread either doesn't care the specific exception type or ignore wasi
  proc exit by themselves. (clear_wasi_proc_exit_exception)
- clear_wasi_proc_exit_exception only clears local exception.
