CMake: Fix using precompiled headers with Objective-C++ files

Browse source 
Compiling .mm files gives error 'Objective C file was disabled in PCH but is currently enabled'.

Enable the OBJCXX language so the Objective-C++ compiler will be detected and used for .mm files instead of the c++ compiler.
Detect if there are .mm files and enable PCH for them too.

Don't set COTIRE_UNITY_SOURCE_EXCLUDE_EXTENSIONS when cotire is not used.
