The existing state of affairs was getting a little unwieldy.
All of LLDB's utility functions and initial configuration was in
the root CMake file. I split this up into 3 separate files and
moved them to relevant subfolders under cmake/modules.
Also, I deleted the add_lldb_definitions() function. It seemed
to be somewhat useless and did not serve any real purpose that
I was able to figure out.
