* Add new, simpler CMake helper functions
... making them more like built-in functions. This makes it possible to
combine other CMake functions in ways that weren't possible with the
original all-in-one approach.
This includes:
* firebase_ios_add_executable
* firebase_ios_add_test
* firebase_ios_add_library
All of which can be combined with target_link_libraries, etc.
* Shorten CMake test targets, e.g. firebase_firestore_util_test => firestore_util_test
* Remove CMake file inclusion check
Now that we're committed to using globs for finding sources, this check
is incompatible and no longer useful.
