esp32: Allow SPIRAM_MALLOC_RESERVE_INTERNAL to span multiple regions of memory

Browse Source 
- Allocate this pool after main_task is running, so it can use startup stack RAM
- Raise the maximum allowed value in KConfig to 256KB
- Based on forum discussions https://esp32.com/viewtopic.php?f=2&t=6550&sid=76cd27bda76c6d0e83d3fcc9ec30c650&start=10#p28253
