Exclude files from unity build to resolve Android's build

There are several duplicate symbols defined across android source files.
For now, excluding the conflicting files allows us to continue working
on bringing unity build to CI. I added some explanation and TODO's on
what I think can be done for resolving the conflict.

Pick-to: 6.5
Task-number: QTBUG-109394
