Add configurable extra memory (#3513)

Browse Source 
* Add configurable extra memory

* lowercase getter and setter

* Refactor memory setup to configure maximum memory limits at runtime

* sir clang offnir, the all-formatting

* Correctly update BackingSize on W*ndows too

* small format change

* remove total_memory_to_use from the header

* i have no idea how to name this commit
"addressing review comments" is a good name i guess

* Do not include extraDmem in the general config
