Subject: Generate CMake frameworks from podspecs (#1531)

* Rename utils.cmake to cc_rules.cmake

This makes it less of a dumping ground

* Fix sign mismatch in FIRApp

* Implement a podspec_framework CMake function

... that generates a CMake framework library target from a podspec.

* Remove manual CMake scripts for xcodebuild
