This patch always defines the cxx_shared, cxx_static & other top-level targets. However, they are marked as EXCLUDE_FROM_ALL when we don't want to build them. Simply declaring the targets should be of no harm, and it allows other projects to mention these targets regardless of whether they end up being built or not. This patch basically moves the definition of e.g. cxx_shared out of the `if (LIBCXX_ENABLE_SHARED)` and instead marks it as EXCLUDE_FROM_ALL conditionally on whether LIBCXX_ENABLE_SHARED is passed. It then does the same for libunwind and libc++abi targets. I purposefully avoided to reformat the files (which now has inconsistent indentation) because I wanted to keep the diff minimal, and I know this is an area of the code where folks may have downstream diffs. I will re-indent the code separately once this patch lands. This is a reapplication of 79ee0342dbf0, which was reverted in a3539090884c because it broke the TSAN and the Fuchsia builds.
