Use CMake source_group function to organize tangram-core files in Xcode (tangrams#1989)

* Use CMake source_group function to organize tangram-core files in Xcode

Requires listing all headers in tangram-core, but now Xcode can index header contents and match them with their cpp counterparts!

* Check CMake version >= 3.8 for source_group
