cmake: increase threshold for stack probes The /Gs argument controls the number of bytes that local variables can occupy before a stack probe is initiated. By setting it to a huge value, no calls to __chkstk are inserted. This change is needed for the classic Intel C compiler to build SDL with -DSDL_LIBC=OFF.
