Revert the recent batch of changes to the CMake build of libclc that introduced
significant breakage, notably:
- standalone builds no longer working
- broken symlinks being installed
These changes are nontrivial and were made shortly prior to the branching
point, so it's better to defer them to 22.x and fix properly than attempt to
apply more ad hoc fixes.
Fixes #149659
Fixes #149437

Subject: [PATCH 1/5] Revert "[libclc] Move CMake for prepare_builtins to a
subdirectory (#148815)"
This reverts commit 8a7a64873b13e6fd931b748fbf50b3da26fe7fca. It broke
standalone builds since the necessary variables are now limited in scope
to `libclc/utils` while they are used in the top-level CMakeLists.

(#146833)"
This reverts commit 81e6552a3d6835c4e10eb981402febfac9df6156. This
change caused libclc to start installing broken symlinks that contain
absolute paths to the build directory rather than relative paths
within the install directory.
