Original commit message:

    d8: Make in process stack dumping optional

    Adds a flag (--disable-in-process-stack-traces) to not install
    signal handlers so that e.g. ASan signal handlers will work.

    This flag mirrors chromium's one.

Since V8 5.9 V8 installs a default signal handler for some signals
when creating a default platform instance that prints a stack trace.

However, Node already does the same thing, so it would seem like the
two different stack traces would be printed; also, the V8 handler
would lead to a `SIGSEGV` under some circumstances, rather than
letting the abort continue normally.

Resolve this by disabling V8’s signal handler by default.

Fixes: nodejs#13865
