PR jit/64721: toplev: don't install signal-handlers when running within
libgccjit

gcc/ChangeLog:
    PR jit/64721
    * main.c (main): Construct toplev instances with init_signals=true.
    * toplev.c (general_init): Add param "init_signals", and use it to
    conditionalize the calls to signal and host_hooks.extra_signals.
    (toplev::toplev): Add param "init_signals".
    (toplev::main): When invoking general_init, pass m_init_signals
    to control whether signal-handlers are installed.
    * toplev.h (toplev::toplev): Add param "init_signals".
    (toplev::m_init_signals): New field.

gcc/jit/ChangeLog:
    PR jit/64721
    * jit-playback.c (gcc::jit::playback::context::compile): Construct
    toplev instances with init_signals=false.
