[cmake] Add support for using the standalone leaks sanitizer with LLVM.

This commit causes LLVM_USE_SANITIZER to now accept the "Leaks" option. This
will cause cmake to pass in -fsanitize=leak in all of the appropriate places.

I am making this change so that I can setup a linux bot that only detects
leaks.
