[C++] Fix bundled abseil and homebrew formula

[asfimport]

The homebrew-r-brew nightly job has been failing since the ARROW_GCS flag was turned on in ARROW-14892. The failure is an undefined absl symbol

** testing if installed package can be loaded from temporary location
Error: Error: package or namespace load failed for ‘arrow’ in dyn.load(file, DLLpath = DLLpath, ...):

I encountered the same error when working on R bindings for GCS in ARROW-16510. There are two issues:

• The bundled abseil cmake build macro is incomplete, possibly as a result of a merge conflict
• The homebrew formula should be updated to use the brew bottles for the google-cloud-cpp dependencies (there is no formula for it itself) rather than bundle everything
