heap: Modify the memory type of the memory used as startup stack when memory protection is enabled

Browse Source 
If memory protection is enabled on esp32c3 and esp32s3, we don't want to the heap component to see
the startup stack memory as D/IRAM but as DRAM only. Introduce a new type to make this possible in
the same fashion the regular D/IRAM regions are handled.
