C++ has a concept of Primitive which holds in the type graph. However we don't currently expose this information to the end user. Expose this from the OIL iterator to allow future features like primitive rollups. This affects containers like maps which have a fake `[]` element with no type. They use this to group together the key/value in a map and to account for any per element storage overhead. Currently the decision is to make the fake `[]` element a primitive if all of its children are primitives. This allows for more effective primitive rollups if that is implemented. This implementation detail may be changed in future. Test Plan: - CI - Updated simple tests.
