Subject: [PATCH] [CMake] Build debugserver & debugserver_nonui

When building for iOS we build two variants of debugserver. One which supports UI functionality like Springboard for launching applications, and one which does not.

This patch adds support for building debugserver with and without UI support libraries being available.
