[opt-remark] Add support for emitting opt-remark bitstream artifacts when building benchmarks with cmake.

Browse Source 
I didn't do this for swiftpm as well since when I tried passing this via
unsafeFlags to swiftpm, swiftpm just created the opt-remarks in my source
directory instead of next to the .o in the build directory. A problem for
another time.
