[CMake] Refactor and cleanup generating and installing symlinks to tools. Summary: This change generalizes symlink generation and makes symlinks to tools obey LLVM_TOOLCHAIN_TOOLS. It makes it so that if you exclude llvm-ar from LLVM_TOOLCHAIN_TOOLS you don't end up with broken symlinks to llvm-lib and llvm-ranlib in your install.

# We need to execute this script at installation time because the
# DESTDIR environment variable may be unset at configuration time.
# See PR8397.
[CMake] Cleaning up and generalizing the LLVMInstallSymlink script so that it can be used for libraries too. In order to resolve PR25059, we're going to need to be able to generate symlinks to libraries manually, so I need this code to be reusable. llvm-svn: 250573
