OffsetContainer serialization (#1093)

* OffsetContainer with unit tests.

* State serialization working with OffsetContainer.

* Fixes to make work with OffsetContainer.

* Added OffsetContainer documentation.

* Remove RelativeContainer.

* Fix problem with + on Offset32Ptr on windows x86 target.

* * Made OffsetBase a base class of OffsetContainer.
* Added MemoryOffsetBase to just handle being a chunk of memory.

* * Use operator[] to access contents of OffsetContainer

* Fix the type hash to work across different size_t sizes.

* Fixed some Offset type related comments.

* Fix bug around using asBase, because it returns a reference just using 'auto' will means it becomes a value type.
Remove assignment and copy ctor from OffsetBase.

* Evaluation order of assignment can lead to wrong behavior with Offset32Ptr/raw pointers. Document the fact, and fix in StateSerializeUtil.
