[cmake] Add support for specifying the number of parallel link jobs for swift. I am going to use the link job for limiting swift lto compile time. The reason not to use the same variables as LLVM (i.e. LLVM_PARALLEL_LINK_JOBS) is that Swift since it is compiling more IR may have a larger memory representation implying less parallel linking jobs than LLVM can be used on bots.
