### Before
Case 1: Handler catches the exit signal and do not pass it forward. As
result xonsh could be suspended by OS or crash. Also exit code is wrong.
See repeatable examples with SIGHUP in
https://github.com/xonsh/xonsh/issues/5381#issuecomment-2097961804.
Case 2: From bash/zsh as login shell run xonsh. Then send quit signal to
xonsh. The terminal state will be broken: disabled SIGINT, mouse pointer
produces mouse state codes.
### After
Case 1: Xonsh exit normally with right exit code. Fixed#5381#5304#5371.
Case 2: After exiting with right exit code the state of the terminal is
good.
