Before the test reorganization, everything was part of a single test suite with a single module cache. Now that things are properly separated this is no longer the case. Only the shell tests inherited the logic to properly configure and wipe the module caches. This patch adds that logic back for the API tests. While doing so, I noticed that we were configuring a Clang module cache in CMake, but weren't actually using it from dotest.py. I included a fix for that in this patch as well.

LLDB API Tests
This directory only exists for the lit test driver. The actual tests live in
the tests directory in top level LLDB directory.
