Log:
[CMake] NFC. Add clang-tablegen-targets utility target
By creating this target other projects that depend on clang-generated headers
(like LLDB) will no longer be order-dependent on Clang being processed by CMake
first.
Also, by creating a dummy of this target in ClangConfig.cmake, projects that
can build against out-of-tree clang can freely depend on the target without
needing to have conditionals for if clang is in-tree or out-of-tree.
