[roll] Roll fuchsia [kernel][vm] Stack canary

Adds a stack canary, controllable via the kernel cmdline, that writes a
small canary pattern near the end of a stack to, heuristically,
determine if a high watermark of stack usage was exceeded.

Detection is performed on stack / thread deletion and so will not find
excessive stack usage on forever executing threads, or stack usage that
allocated, but did not write to, the portion of the stack where the
canary was. This limitations can be improved upon in future CLs.
