lib/stackdepot: annotate init and early init functions
Add comments to stack_depot_early_init and stack_depot_init to explain
certain parts of their implementation.
Also add a pr_info message to stack_depot_early_init similar to the one
in stack_depot_init.
Also move the scale variable in stack_depot_init to the scope where it
is being used.
