MDEV-16660: Increase the DEFAULT_THREAD_STACK for ASAN

To allow cmake -DWITH_ASAN=ON to work out of the box when using
newer compilers, we must increase the default thread stack size.

By design, AddressSanitizer will allocate some "sentinel" areas in
stack frames so that it can better catch buffer overflows, by trapping
access to memory addresses that reside between stack-allocated variables.

Apparently, some parameters related to this have been changed
recently, possibly to allow -fsanitize=address to catch more errors.

   We need to have at least 256K stack to handle calls to myisamchk_init()
   with the current number of keys and key parts.
