[Test][Intro] Fix introspection test on API changes for Xcode 9 Beta 1 (#2191)

* [Test][Intro] Fix introspection test on API changes for Xcode 9 Beta 1

* [introspection] Fix feedback from PR and bot tests

Removed XAMCORE_4_0 checks from our api definition, and added
a file with stubs for all of them instead. Cleaner binding file
and easier to remove in the future

Fixed introspection also for mac by moving some check into base test definition

* [CoreImage] Add CoreImage stubs so introspection test are happy

These need to be manually reviewed by whoever takes CoreImage framework
tracked in bugzilla so we do not forget

* Do the same API cleanup as in NSUnit

* [test][introspection] Enable MtouchNoSymbolStrip for device builds in order to avoid linking symbols meeded by test (#2196)

Rolf Kvinge [8:59 AM]
@dalexsoto the fix is to not strip the executable please PR that
(it should probably go into master as well). This probably started
happening when Jeff implemented support for stripping debug builds
(previously the setting was ignored)

* [foundation] Provide better messages

* [CoreImage] Fix Availability of CIEdgePreserveUpsampleFilter
