lib/stackdepot: rename stack_depot_disable
Rename stack_depot_disable to stack_depot_disabled to make its name look
similar to the names of other stack depot flags.
Also put stack_depot_disabled's definition together with the other flags.
Also rename is_stack_depot_disabled to disable_stack_depot: this name
looks more conventional for a function that processes a boot parameter.
No functional changes.
