Original commit message:

    Fixing a possible freeze on abort with 'v8_win64_unwinding_info'

    Win64 unwind data can specify a language-specific handler function which is
    called as part of the search for an exception handler, as described in
    https://docs.microsoft.com/en-us/cpp/build/exception-handling-x64?view=vs-2019.
    This is used for example by Crashpad to register its own exception handler for
    exceptions in V8-generated code.
    There is a problem in the code that may cause a freeze on abort: in file
    \deps\v8\src\unwinding-info-win64.cc in function CRASH_HANDLER_FUNCTION_NAME the
    line:
        return EXCEPTION_CONTINUE_SEARCH;
    should be
        return ExceptionContinueSearch;

    These constants are both used in the context of Win32 exception handlers, but
    they have different semantics and unfortunately different values:
    EXCEPTION_CONTINUE_SEARCH (=0) should be returned by an exception filter
    while a language-specific handler should return an EXCEPTION_DISPOSITION value,
    and more precisely ExceptionContinueSearch (=1) in this case.
