New Pull Request Checklist

Issue Description

Currently developer can't create a query to compare against a pointer directly. Similarly, the related query can't take a ParseObject directly.

In addition, add os(Windows) so SDK compiles correctly for Windows.

Related issue: #n/a

Approach

Make SDK easier to use by taking a pointer directly.

TODOs before merging

• Add tests
• Add os(Windows) so SDK compiles correctly for Windows.
• Add entry to changelog
• Add changes to documentation (guides, repository pages, in-code descriptions)
