protect: move us_heap to userspace_data_s

Browse Source 
Refactor heap pointer storage by moving us_heap field from userspace_s
to the nested userspace_data_s structure, enabling future extensibility
of user-space data without modifying the core userspace_s interface across
all board-specific implementations.
