COM parameter ownership doc

[jtschuster]

Creates a public document for detailing value ownership transfer across COM method calls.

The formatting style and wording needs to be changed and more examples need to be added, but I want to start with feedback on if this is the right way to think about COM ownership and explain it to users.
