Cygwin: pty: Fix failure to clear switch_to_nat_pipe flag. After the commit fbfea31dd9b9, switch_to_nat_pipe is not cleared properly when non-cygwin app is terminated in the case where the pseudo console is disabled. This is because get_winpid_to_hand_over() sometimes returns PID of cygwin process even though it should return only PID of non-cygwin process. This patch fixes the issue by adding a new argument which requests only PID of non-cygwin process to get_console_process_id().

Cygwin: Fix segfalt when too many command line args are specified. Previously, the number of command line args was not checked for cygwin process. Due to this, segmentation fault was caused if too many command line args are specified. https://cygwin.com/pipermail/cygwin/2023-August/254333.html Since char *argv[argc + 1] is placed on the stack in dll_crt0_1(), STATUS_STACK_OVERFLOW occurs if the stack does not have enough space. With this patch, char *argv[] is placed in heap instead of stack and ARG_MAX is increased from 32000 to 2097152 which is default value of Linux. The argument length is also compared with ARG_MAX and spawnve() returns E2BIG if it is too long.
