Split cloudbuild build-all.yaml into 2 separate build commands to avoid length overflow

[andy31415]

Build fails otherwise due to too long arguments, it says:

Your build failed to run: generic::invalid_argument: invalid build: invalid .steps field: build step 2 arg 0 too long (max: 4000)

Will merge since CI cannot validate cloudbuild compilations.
