integration-test: Remove runtime toolchain deps
Move the use of clang and llvm-objcopy from run-time to build-time. This
allows the integration tests to run on VMs with simpler userlands.

Create a new CI job to build the integration tests separately from
running them. Ship them from that job to the runner job using github
actions artifacts.
