Switch to variable-size stacks
Increase stack size slightly for vboot hash task since the vboot
SHA256 function allocates ~300 bytes of stack data. Reduce stack size
for watchdog, power LED, and a few other tasks with simple call trees
where we can be sure an error path isn't going to blow past the
reduced stack.
This frees up ~1KB of RAM on STM32.
BUG=chrome-os-partner:13814
BRANCH=all
TEST=boot system; shmem should show more unused RAM; taskinfo should show
tasks still have unused stack
