lib/stackdepot: use fixed-sized slots for stack records
Instead of storing stack records in stack depot pools one right after
another, use fixed-sized slots.
Add a new Kconfig option STACKDEPOT_MAX_FRAMES that allows to select the
size of the slot in frames. Use 64 as the default value, which is the
maximum stack trace size both KASAN and KMSAN use right now.
Also add descriptions for other stack depot Kconfig options.
This is preparatory patch for implementing the eviction of stack records
from the stack depot.
