This pull request fixes #3162

Description

The was that we didn't support extracting type name from the ODataJsonElementValue for the context URL when writing top-level properties. This PR handles that as follows:

• for primitives, use the corresponding Edm primitive type name. For numbers, this returns Edm.Double since we can't be use of the numerical type (int32, double, decimal, etc.?) based on the value kind alone.
• for arrays and objects, return Edm.Untyped. This can be problematic and needs to be re-evaluated to see if there's a better option.
• for null, throw an exception by default since top-level nulls are not supported by default, but with the right compatibility flag, we can return Edm.Null (TODO: add test for the latter case)

Checklist (Uncheck if it is not completed)

• Test cases added
• Build and test with one-click build and test script passed
