refactor: allow usage of NiPoint3 and NiQuaternion in constexpr context (#1414)

Browse Source 
* allow usage of NiPoint3 and NiQuaternion in constexpr context

* removed .cpp files entirely

* moving circular dependency circumvention stuff to an .inl file

* real world usage!!!!!

* reverting weird branch cross-pollination

* removing more weird branch cross-pollination

* remove comment

* added inverse header guard to inl file

* Update NiPoint3.inl

* trying different constructor syntax

* reorganize into .inl files for readability

* uncomment include

* moved non-constexpr definitions to cpp file

* moved static definitions back to inl files

* testing fix

* moved constants into seperate namespace

* Undo change in build-and-test.yml

* nodiscard
